Abstract

Steel plate shear wall is a lateral force resisting system, of two types of stiffened and unstiffened. The manufacturing of the stiffened type is time-consuming, costly, and needs more supervision; because of many executive details. Steel plate shear wall with a corrugated web is a new system that has been considered as an alternative for all types of stiffened walls. Corrugated sheets have complex geometry and their modeling is difficult in existing conventional software. To overcome the complexity of the modeling of corrugated sheets, flat sheets with orthotropic material properties can be replaced instead of these sheets by the help of material mechanics science. This research aims to provide a specific process for calculating the mechanical properties of an alternative orthotropic flat sheet to the corrugated sheet, and to study the accuracy of the orthotropic model in predicting the monotonic and cyclic behavior of corrugated shear walls. For this purpose, the results of the analyses of the orthotropic and trapezoidal corrugated models of the steel plate shear wall with different characteristics of the waves are compared and the accuracy of the proposed method is examined. Finally, by studying the results of different models in Abacus, it was found that the proposed method was able to predict the monotonic and cyclic behavior of trapezoidal corrugated steel shear wall.
