Abstract
This research is mainly focussed on statistical assessment and analysis of the accuracy of predicting the shear resistance of the fiber-reinforced polymer (FRP) sheets for prestressed concrete beams strengthened by FRP sheets presented in the current design guidelines. The evaluation of the current prediction models is based on a database of experimental results from the previous and current author’s research. The specifications of the beams are diverse and wide enough such as beam types (prestressed concrete beams using bonded tendons - BPC beams and unbounded tendons - UPC beams), cross-section shape, concrete strength, effective prestress stress, and shear span to depth ratio - a/d …. The results of the evaluation have shown that the formulas in recent design guidelines overestimated the shear contribution of FRP sheets for prestressed concrete beams.
