Interpreting the effects of geometric dimensions and material properties on performance of steel shear walls

چکیده مقاله

Shear panels have been known as one of the most durable and stiffest lateral load-bearing systems in the structures for a long time. According to high stiffness and ductility of these systems, a large number of studies have been performed on them. In this study, the effect of changes in thickness, length to height ratio and yielding stress of constituting materials on ultimate strength of steel shear walls was investigated. For this purpose, numerical models of 21 shear wall systems were provided using ANSYS finite element software and non-linear analysis of wall ultimate load. Based on the obtained results, it may be mentioned that increasing wall thickness and yield stress of materials will increase the ultimate strength of system. In addition, increasing the panel width and keep the height constant will increase the ultimate wall shear strength which is due to tendency of wall behavior to shear performance rather than bending performance that improves its condition.
