1 Introduction

As a new alternative lateral force resisting system (Cao et al., 2016; Gholizadeh & Yadollahi, 2012; Hosseinzadeh & Aziminejad, 2017; Zhao et al., 2017), a corrugated steel plate shear wall (CSPSW) possesses enhanced in-plane and out-of-plane stiffness, high strength, ductility, and stable hysteretic characteristics owing to the excellent cross-sectional characteristics of its CSP, as shown in Fig. 1. The CSPSW with inelastic buckling of CSPs could restrict the elastic out-of-plane buckling of in-filled steel plates with appropriate CSPs at a low cost (Cao & Huang, 2018; Driver et al., 2006; Easley & ASCE., 1969; Yi et al., 2008), and lateral displacement could be restricted in the structures used the shear walls as the lateral resisting systems. So, the CSPSWs with inelastic buckling of CSPs could be applicable in high buildings or the structures with strict requirements of lateral displacement. So, it is necessary to investigate the seismic behaviour of the CSPSWs with inelastic buckling of CSPs for the potential shear walls in high buildings.

Profile of a CSP

Recently, researchers have begun to study the mechanical properties of thin CSPSWs, which buckle in the stage of elastic loading, including ultimate strength, failure modes, and key parameters. Kalali et al., 2015, 2016 investigated the hysteretic performance of CSPSWs. The results indicated that an appropriate design of boundary frame members can yield high stiffness, strength, and cyclic performances of CSPSWs. Berman et al., 2011 compared the performances between a CSPSW and a flat steel plate shear wall (FSPSW), which indicated that the former showed a lower demand for the strength and stiffness of surrounding frames. Emami et al., 2013 investigated the behaviour of CSPSWs with thin CSPs, which showed elastic buckling in the early elastic loading stages and a tension field action failure mode. Shon et al., 2017 conducted an experimental study to investigate the effects of CSP placement on the buckling modes of CSPSWs. The results showed that the failure mechanism varied according to the arrangement of CSPs in the surrounding frames. The CSPSW specimen with a vertical CSP demonstrated a local buckling followed by global buckling, whereas that with a horizontal CSP presented global buckling. Farzampour et al., 2015 proposed an expression to estimate the ultimate capacity of a CSPSW with openings by linear regression analysis.

Researchers have investigated the buckling strength of thin CSPSWs. Dou et al., 2016, 2018 examined the elastic shear buckling and post-buckling strength of sinusoidally CSPSWs by FEA and established fitting equations for the elastic buckling capacity and post-buckling of the shear walls. Wei et al., 2015 studied the elastic shear buckling strength of CSPSWs with edge stiffeners by FEA. The results showed that the local buckling of the corner could affect the capacity of the shear walls. Farzampour et al., 2015 derived the elastic buckling and ultimate capacity of CSPSWs based on the plate–frame interaction (PFI) method. The result showed that the PFI method could accurately predict the elastic buckling and ultimate capacity of CSPSWs with interactive buckling.

As presented above, previous studies primarily focused on the elastic and-post buckling strengths of thin CSPSWs. However, studies that elaborate the hysteretic performance of CSPSWs with larger thickness corrugated steel plates with inelastic buckling are fewer, of which buckling modes are inelastic buckling. This paper addresses the seismic behaviour of the CSPSWs with inelastic buckling under lateral loads. A numerical model was developed to simulate the performance of CSPSWs with inelastic buckling of CSPs. Buckling modes, post buckling, failure modes of the shear walls were discussed. Bedsides these, the effects of geometric parameters on the seismic behaviour of CSPSWs subjected to lateral loads are investigated as well, such as, height–thickness ratio, aspect ratio, horizontal panel width, corrugation angle, initial imperfections. And the minimum stiffness of the CSPSWs are also discussed. In addition, the ductility, energy dissipation lateral deformation capacity and weak parts of the CSPSW are evaluated to evaluate the seismic performance of the CSPSW with inelastic buckling of the CSP.

2 Computational Study

2.1 Finite Element Model

A single-bay, one-storey CSPSW specimen with a corrugated steel plate horizontally arranged is designed. The specimen size and loading conditions are shown in Fig. 2. In the shear wall structure, the connections between columns and top and bottom beams are rigid. The out-of-plane deformations of the frames are constrained by lateral braces. The base of bottom beam was fixed.

Fig. 2
figure 2

Configuration of a CSPSW

A numerical model is developed to simulate the seismic performance of a CSPSW using finite element (FE) software ANSYS. A four-node element (shell 181) with six degrees of freedom at each node, which supports full and reduced integration schemes, is adapted to simulate the nonlinear behaviour of CSPSWs. The bilinear kinematic and ideal inelastic model of materials of frames and CSPs are adopted in Fig. 3. The steel elastic modulus of the frames and the CSPs are 2.06 × 1011 N/m2. The yield strength of CSPs are 370.2 Ma. The yield strength of the frames are 400 Ma, and the ultimate strength of frames are 570 Mpa.

Fig. 3

Constitutive model of the CSPSW material

For the bottom boundary conditions of the CSPSWs are fixed. The out-of-plane initial imperfection value of the CSP is set as one thousandth of the width of the CSPs, which is taken into consideration for the manufacturing and installation errors of the CSPs. When the element sizes of models are 20 mm × 20 mm, the results of FE models are insensitive to the element size. The meshed finite element model is shown in Fig. 4.

2.2 Verification Study

The rationality and accuracy of the FE model is verified by a well-known test. A single-bay, two-storey CSPSW specimen test was conducted by (Li & Qiuhong, 2016), of which buckling mode is inelastic buckling modes of CSPs.

In the specimen, the sections of the columns are H-200 mm × 200 mm × 8 mm × 12 mm, and of the top beams H-175 mm × 175 mm × 8 mm × 10 mm, and of the middle beams H-175 mm × 175 mm × 8 mm × 10 mm respectively. The thicknesses of the CSPs are 2 mm. The wave length of the CSPs are 200 mm, the corrugation depth of the horizontal panels 20 mm, and horizontal panel width 50 mm.

The comparison of load—displacement curves and failure modes under cyclic loading between the FE model and the CSPSW specimen are carried out in Figs. 5 and 6.

Fig. 5

Validation of FE model results

Fig. 6
figure 6

The verification of failure modes between the FE model and the test results (Li & Qiuhong, 2016)

Figure 5 shows the comparison of hysteresis curves between the FE model and the test. The maximum relative errors in the ultimate capacity and the corresponding lateral displacement to ultimate capacity of between the FE model and the test are 7.0% and 13.9%, and the response of the FE model are higher than those of the test. The results of the former and the latter are in good agreement. According to (Li & Qiuhong, 2016), the failure modes of the shear wall is tear failure of bottom the CSP owing to the tension field, which is along the diagonal of the infilled plate, and the phenomenon is also observed in the FE model in Fig. 6. Therefore, the FE model established in this paper could well simulate the hysteretic behaviour of the CSPSW.

3 Parametric Analyses and Discussions

In this section, the effects of geometric parameters of the height—thickness ratio, aspect ratio, horizontal panel width, corrugation angle, initial imperfection, and surrounding frame stiffness on CSPSWs are investigated. The details of the parameters study of CSPSWs are shown in Table 1.

Table 1 Key parameters table

3.1 Height—thickness ratio

The height—thickness ratio that is considered to examine the effect on the structure performance of the CSPSW, and five specimens with different height to thickness ratios 100, 200, 300, 500 and 700 are used, with corresponding corrugated plate thickness \(t_{w}\) 10.0 mm, 5.0 mm, 3.3 mm, 2.0 and 1.4 mm respectively. In these models, the sections of the columns are H-250 × 250 × 9 × 14 and of the beams H-200 × 100 × 5.5 × 8 respectively. The geometric characteristics of these CSPs are shown in Table 2. The hysteresis curves with various height—thickness ratios are shown in Fig. 7.

Table 2 Geometric characteristics of CSPSWs
Fig. 7
figure 7

Hysteresis curves of CSPSWs with different height—thickness ratios

As can be seen in Fig. 7, the shapes of hysteresis curves are spindle. With the decrease of the height—thickness ratio, the shape of the hysteresis curves of the wall is much fuller. When the height—thickness ratio is 700, obvious pinching is observed. The ultimate shear stress is 170.2 MPa, of which ultimate shear stress is less than 0.80 \(\tau_{y}\), and the buckling mode of the CSP is elastic buckling. However, when the height—thickness ratio \(\lambda\) is less than 500, there are no obvious strength and stiffness degradations in these specimens. The buckling mode of the CSPs are inelastic buckling of CSPs (\(\lambda \le 500\)), and the shapes of the CSPSWs are different from those of the FPSWs and the thin CSPSWs (Emami et al., 2013; Zhang et al., 2018). The height—thickness ratios of corrugated steel sheet in CSPSW specimens (Emami et al., 2013) vary from 0.752 to 1.78 mm, and the corresponding height—thickness ratios \(\lambda\) vary from 700 to 1700. The ultimate shear stress of these CSPSWs in the tests are form 30–35 Mpa, which are much lower than the yield stress of the infilled plates, and the specimens show obvious pinching and degradations in hysteretic curves, of which failure modes are elastic buckling. Therefore, the shapes of the hysteretic curves are much thinner than those of CSPSWs with height—thickness ratios \(\lambda\) from 100 to 500 in this paper. With the increase of height—thickness ratio of a CSP, the shear stress of infilled plates decreases (Fig. 8).

Fig. 8
figure 8

Skeleton curves with various height to thickness ratios

The similar phenomena are also observed in the tests conducted by Massood (Emami et al., 2013), and the height—thickness ratios of CSPSW specimens \(\lambda\) are 1600. In the reference (Emami et al., 2013), the ultimate shear stresses of the CSPs are approximately 100 Mpa, and the corresponding drift ratios are approximately 0.06. It is indicated that drift ratios corresponding to the ultimate strength of the specimens in the tests are much larger than those of the CSPSWs with inelastic buckling of CSPs. This is largely due to larger compression capacity of tension field of the CSPSWs than those of the FPSWs and thin CSPSWs. The larger the height to thickness ratio is, the fuller shape of the hysteresis curves of the CSPSW is.

Figure 9 shows the typical buckling modes of the CSPSW with inelastic buckling of the CSP (\(\lambda { = }300\)). From Fig. 9, the typical buckling mode of the CSPSW is the inelastic buckling along the diagonals of the CSP. And this is different from that of the CSPSW with small thickness of a CSP and a FPSW (Emami et al., 2013; Zhang et al., 2018), of which buckling mode is elastic buckling shown in Table 3.

Fig. 9

Inelastic buckling of the CSP (\(\lambda { = }300\))

Table 3 Results of CSPSWs with different—thickness ratios

The failure modes of CSPSWs are associated with height—thickness ratios. When the height—thickness ratios of the CSPs are 300—700, the failure modes are failure of tension field formed in the CSPs, of which buckling modes are inelastic buckling, and the way of resisting the lateral loads are tension field shown in Fig. 10b, c. The failure modes of the CSPSWs are consistent with those of the CSPSW specimens with CSP elastic buckling conducted by (Emami et al., 2013). Compared with the CSPSW (\(\lambda { = 300}\)), the tension field developed more fully shown in Fig. 10c. However, when the height—thickness ratio of the CSPs is less than 200, of which buckling modes is yielding of the CSP, and the way of resisting the lateral loads is pure shear shown in Fig. 10a.

Fig. 10
figure 10

Failure modes of CSPs with different ratios

Figures 11 and 12 show the typical trajectory of principal stress and out-of-plane deformation of the CSPs under the failure modes respectively. It is can be seen that the failure modes of the CSPSW are yielding of the tension field strips along the diagonals in the whole CSP, of which inclination angle of the tension field strips is about 45°. And the corners in the CSP are the earliest parts to enter the yield stage. So, the corners of the CSPs in shear walls should be strengthened. In practical projects, the corners of infilled plates are usually to be strengthen by reinforcing plates to prevent the stress concentrating. Besides this, the other effective method is cutting the corners of infilled plates in some FSPSWs (Fig. 13).

Calculation of energy dissipation coefficient

Skeleton curves and hysteretic energy dissipation curves with height—thickness ratios are shown in Figs. 8 and 14 respectively. The lateral deformation capacity of shear walls is an important index of the ductility of shear walls. After the ultimate strength, the load decrease to the 85 percent of the ultimate strength of the CSPs, the lateral ultimate deformation \(\Delta_{u}\) are 60.5 mm, 42.13 mm, 28.08 mm, 15.04, and 8.24 mm respectively, with the corresponding height-thickness ratios 100, 200, 300, 500 and 700 respectively. The lateral ultimate deformation \(\Delta_{u}\) shows a negative correlation with the height-thickness ratio. It is because that the lateral shear stiffness of the shear walls is more largely weaken when the CSPs with larger height—thickness ratios buckle. Similar as shown in Fig. 8, the shear walls experience earlier and sharper decrease in strength resistance with the increase of height—thickness ratios.

Fig. 14
figure 14

Energy dissipation coefficient curves with different height—thickness ratios

The ductility coefficient \(\mu\) could be used to describe the lateral plastic deformation capacity, which are expressed as:

$$\mu = \frac{{\Delta_{u} }}{{\Delta_{y} }}$$
(1)

where \(\Delta_{{\text{y}}}\) represents the yield deformation of CSPSWs, \(\Delta_{u}\) ultimate displacement.

The ductility coefficient \(\mu\) of the CSPSWs are 16.1, 12.5, 9.0, 4.9 and 3.0 respectively, when the heigh to thickness ratios are 100, 200, 300, 500 and 700 respectively. When the height—thickness ratios are less than 500, the ultimate lateral deformation \(\Delta_{u}\) exceed 0.02. This means that this kind of shear walls show good lateral plastic deformation capacity with appropriate height-thickness ratios.

Besides these, the lateral deformation capacity is very import to the energy dissipation of shear walls. Energy dissipation coefficient \(E_{{\text{n}}}\) could be used to evaluate the dissipation capacity, and the index \(E_{e}\) could be expressed as:

$$E_{{\text{n}}} = \frac{{S_{{ABC{\text{DA}}}} }}{{S_{OBE} + S_{OAF} }}$$
(2)

\(S_{ABCDA}\) represent the area enclosed by hysteresis curve in Fig. 13, \(S_{OBE} + S_{OAF}\) represent the areas of the triangles OBE and OAF in Fig. 13.

The energy dissipation coefficient curves are shown in Fig. 14. The figure shows that the coefficient \(E_{n}\) decreases with the increase of the height—thickness ratio. This is because the thickness of the infilled CSPs could significantly improve the energy consumption capacity of the shear walls.

3.2 Aspect Ratio

In this part, four specimens with different aspect ratios, 1.5, 2.0, 2.5, and 3.0 were used to study the effect of aspect ratios on cyclic performance of the CSPSW. In these models, aspect ratios were adjusted by changing the CSPs width \(B\), with height of these models \(H\) unchanged. The geometric characteristics of these CSPs are shown in Table 4.

Table 4 Geometric characteristics of CSPSWs

Figure 15 shows that the shapes of hysteresis curves become much thinner with the increase of aspect ratios, and when the aspect ratios reach to 2.0, and the pinching phenomena become obvious. Buckling capacity and ultimate capacity of CSPs decrease with the increase of aspect ratios. This is because the buckling capacity decrease with the increase of the aspect ratio.

Fig. 15
figure 15

Hysteresis curves of CSPSWs with different aspect ratios

The skeleton curves of the hysteresis curves with aspect ratios are shown in Fig. 16. As can be seen from the figure, the ultimate strength of the CSPs decreases with the increase of the aspect ratio B/H As the CSP width of increases, the constrains of surrounding frames on CSPs become weaker, so the average value of ultimate stress in the transverse section of the CSPs reduces. The energy dissipation coefficient shows a reverse trend with the increase of the aspect ratio in Fig. 17.

Skeleton curves with different aspect ratios

3.3 Horizontal Panel Width

To study the effect of the horizontal panel width on the performance of the CSPSW, four specimens with different horizontal panel widths of 30 mm, 50 mm, 70 mm, 90 mm, and 110 mm were used. The geometric characteristics of these CSPSWs are shown in Table 5.

Table 5 Geometric characteristics of CSPSWs

Figure 18 shows that with the increase of horizontal panel width, the shapes of hysteresis curves become much fuller and there are no obvious pinching phenomenon in the these curves. And the strength capacity drops slowly after the ultimate with the increase of the horizontal panel width. The skeleton curves and the hysteresis curves with horizontal panel width are shown in Figs. 19 and 20 respectively. The skeleton curves and hysteresis curves are independent of the horizontal panel width.

3.4 Corrugation Angle

To study the effect of corrugation angles on the behaviour of the CSPSW, four specimens with different corrugation angles \(\theta\) of 30°, 37.5°, 45°, and 52.5° were used. The geometric characteristics of these CSPSWs models are shown in Table 6.

Table 6 Geometric characteristics of CSPSWs

Figures 21 and 22 show hysteresis curves and skeleton curves of CSPSWs with different corrugation angles of the CSPs. From Fig. 21 and 22, after the ultimate strength, a smaller corrugation angle results in a faster decline in the bearing capacity of the CSP. That’s because when a smaller corrugation angle means a smaller moment of inertia. It can be concluded that the energy absorption capability has a positive relationship with the corrugation angle from Fig. 23.

3.5 Initial Imperfection

To study the effect of initial imperfection on the performance of the CSPSW, four specimens with different initial imperfections of \(\lambda /10000\), \(\lambda /100\), \(\lambda /50\), and \(\lambda /20\) were used. The geometric characteristics of these CSPSWs are shown in Table 7. Figure 24 shows hysteresis curves of CSPSWs with different initial imperfections.

Table 7 Geometric characteristics of CSPSWs
Fig. 24
figure 24

Hysteresis curves of CSPSWs with different initial imperfections

The hysteretic behaviour of the CSPs is insensitive to the initial imperfection shown in Figs. 24 and 25. This is because the initial imperfections have little effect on the buckling and ultimate capacity of the CSPs owing to its own corrugations of CSPs.

Fig. 25

Skeleton curves with various initial imperfections

3.6 Surrounding Frame Stiffness

As the boundary conditions of steel plate shear walls, surrounding frames are essential to the loading mechanism and buckling capacity of shear walls. The Design of Steel Structures (CAN/CSA-S16-09) (Association & CAN, CSA-S, 1601, 2001) and Seismic Provision for Structural Steel Buildings (ANSI/SISC 341–05) (Institute & of Steel Construction. ANSI, AISC34105, 2005) used Montgomer’s (James & Manoj, 2001) research results and suggested that the minimum value of inertia moment of columns should satisfy Eq. (3).

$$I_{{{\text{cmin}}}} \ge 0.00307t_{w} d_{s}^{{4}} /b_{s}$$
(3)

The Eq. (3) is based on the research results of the FSPSW, which is closely related to the compression performance of the infilled steel plates and stiffness of the surrounding frames. However, the CSPs show strong anisotropy in parallel to and perpendicular to waves directions. Besides these, the buckling modes, failure modes, and loading mechanism of the CSPSWs differ from those of FSPSWs. Therefore, the effect of the surrounding frame stiffness on the performance of the CSPSW should be discussed.

In this part, four specimens of CSPSWs (\(\lambda = 300\)) were used for study the effect of surrounding frame stiffness on the hysteretic performance of the CSPSW, with 0.5 \(I_{c\min }\), \(I_{c\min }\), 2 \(I_{c\min }\), and 10 \(I_{c\min }\) respectively. In these models, the corresponding sections of the columns were HW125 × 125 × 13 × 7, HW150 × 150 × 15 × 9, HW175 × 175 × 13 × 7, HW190 × 190 × 14 × 8, HW210 × 210 × 15 × 9, HW230 × 230 × 15 × 10, and HW330 × 330 × 15 × 12 respectively. The load—displacement curves with various columns stiffness are shown in Fig. 26.

Fig. 26
figure 26

Load—displacement curves of CSPSWs with various surrounding frame stiffness

When the surrounding frame stiffness \(I_{{\text{c}}} = 0.5I_{{{\text{cmin}}}}\), there are obvious pinching phenomenon in the load—displacement curves. With the increase of the surrounding frame stiffness, the shapes of the hysteresis curves of the wall are much fuller. When the surrounding frame stiffness reach \(I_{{{\text{cmin}}}}\), the pinching phenomenon disappears. This is because that when column stiffness \(I_{{\text{c}}} < I_{{{\text{cmin}}}}\), the stress of tension field is not uniformly, which decrease from the center tension field strips to the neighbouring tension field strips. However, when the columns stiffness is greater than \(I_{{{\text{cmin}}}}\), the stress of tension field plate of the CSP distribute uniformly, and most of tension field strips yield (Fig. 27).

Fig. 27
figure 27

Skeleton curves with different surrounding frame stiffness

Besides these, bearing capacity and energy dissipation capacity have a positive with the increase of the surrounding frame stiffness. This means that surrounding columns with \(I_{{\text{c}}} \ge I_{{{\text{cmin}}}}\), could provide sufficient supports for the full development of tension fields.

Besides these, the surrounding frames stiffness also plays important in the buckling capacity of the CSPs. As shown in Fig. 28, the buckling capacity of the CSPs increases with increase of the surrounding frame stiffness \(I_{c}\). When the stiffness of the frame \(I_{c}\) is greater than \(I_{c\min }\), the buckling strength of the CSPs tends to be stable. This is primarily because the increase in stiffness of the surrounding columns could more effectively restrict the out-of-plane deformation of the CSPs, resulting in the increase of buckling strength of the CSPs.

Fig. 28
figure 28

Buckling capacity versus frame stiffness curve

It is noticeable that the stiffness of surrounding frame sections should satisfy Eq. (3). Subsequently, the buckling strength and energy dissipation capacity of the CSPSWs tend to be stable, and the surrounding frames provide a sufficient anchoring effect to CSPSWs.

4 Conclusions

The seismic performance of CSPSWs with inelastic buckling of CSPs subjected to lateral loads are investigated in this study. A CSPSW specimen is designed to study the hysterics behaviour of the CSPSWs, and the effects of those key parameters on the hysteretic behaviour of CSPSWs were studied. The main conclusions are as follows:

  1. (1)

    The buckling modes of the CSPSW with inelastic buckling of CSPs are the inelastic buckling along the diagonals of CSPs, and the way of resisting the lateral loads rely on tension field. After the buckling, the CSPSWs could resisting greater load by the tension field. The corresponding failure mode of the CSPSW is failure of the tension field strips along the along the diagonals in the whole CSP, of which inclination angle of the tension field strips is about 45°.

  2. (2)

    The corners in the CSP are the earliest parts to enter the yield stage, and the corners are the first lactation to be destroyed in the shear walls under lateral loads. Therefore, the corners of CSPs in CSPSWs should be strengthened in future designs.

  3. (3)

    The height—thickness ratio has a great effect on the strength of the CSPSWs. When the heigh-thickness ratio exceeds 500, the strength drops significantly after the ultimate strength. This phenomenon also occurs in the CSPSWs with a large aspect ratio. It is suggested that the values of height—thickness ratios and the aspect ratios of the CSPSWs should be restricted in the design of the high buildings. Initial imperfections have little effect on the seismic behaviour of the CSPs owing to its own corrugation.

  4. (4)

    The lateral plastic deformation capacity of the CSPSW decrease with the increase of the height—thickness ratio. And when the height—thickness ratios are less than 500, the ultimate lateral deformation of CSPSW \(\Delta_{u}\) exceed 0.02. It is indicated that the CSPSWs show good lateral plastic deformation capacity with appropriate height-thickness ratios.

  5. (5)

    The surrounding frames stiffness \(I_{c}\) could affected the energy-dissipating capacity and the buckling capacity of the CSPSWs. When the surrounding frame stiffness \(I_{c} \ge I_{c\min }\), the energy dissipating capacity and the buckling capacity of the CSPSWs tends to be stable.
