Abstract

In recent years, the use of steel shear panels as a new and seismic-resisting system has been taken into consideration. Among the advantages of braced steel shear panels, which are one of the types pf steel shear wall systems, compared to common concrete and steel shear walls, it is possible to mention some characteristics such as the possibility of determination of the failure mechanism by changing the dimensions, easily creation of an opening, and being cost-effective. Considering the possibility of using corrugated infill panel in steel shear panels instead of flat steel plates, in this research, the effect of considering residual stresses due to the bending process of trapezoidal corrugated panels on their performance was investigated. Then, multi-purpose ABAQUS finite element software was used for the analysis. Also, the simulation of the bending process was modeled in order to apply the initial residual stress on the infill panel of shear panel models. By comparing the analysis results of systems with and without residual stress, it was found that residual stress reduces the amount of dissipated energy, strength, initial stiffness and ductility, and this reduction varies from 3% to 10% in different parameters.
