Description
Summary:This study was designed to find an analytical formula for predicting the ultimate shear strength of a novel kind of complex steel-concrete shear walls known as double steel plate complex shear wall (DSCSW). The performance of these compound walls is now under research and no adequate design provisions are available. Three types of analytical formulae consisting of full shear yield, local and global shear elastic buckling were proposed and their precisions were investigated. To this end, a comprehensive 3D nonlinear finite element (FE) parametric analysis was performed. To carry out such parametric study, 120 FE models of DSCSWs were simulated and analyzed using ABAQUS package. All models were constructed according to an FE model of a test sample of DSCSW which had been constructed and tested in 2013 by Rafiei. The validity of that FE model was verified by comparing the simulation results with the experimental results. The variables considered in the parametric study were the profiled steel plate thickness, the compressive strength of infill concrete, the yield strength of the profiled steel plate and finally the number of the intermediate fasteners. At the end of this study, it was revealed that the full shear yield formula can provide a good estimation of the shear capacity of this type of shear walls when at least one row of the intermediate fasteners in the mid-height of the wall used for connecting the steel plates to the concrete panel.
