Abstract
The Institute of Steel Structures on Vienna University of Technology is developing a new, extremely slender steel-concrete-steel composite (SCSC) plate which is intended to be used in the substitution of old railway bridges without ballast bed. The plate consists of an unreinforced concrete core sandwiched by two steel plates. Dowel strips, welded alternately to the outer steel plates, work together with the concrete core as shear force connection elements. The static strength of the slab was experimentally investigated in full scale laboratory tests. The next step for a derivation of mathematical models is the FE modelling and analysis including highly sophisticated nonlinear material models. Some of the required material variables cannot be identified by physical strength tests. Therefore, parametric studies and the assessment of the influence of each parameter are necessary to find the “best fitting” parameter combinations.
