A Novel Strip Model to Investigate the Seismic Behavior of Frames Equipped with Composite Steel Shear Walls

چکیده مقاله

The composite steel shear wall (CSSW) consists of a steel shear wall (SSW) attached to a reinforced concrete panel using bolts or connectors. In this way, thick-walled steel plates exhibit a higher load-carrying capacity and are less likely to buckle out of the plane. This paper develops a new analytical strip model for 3, 8 and 15 floors frames equipped with CSSW as well as traditional steel shear walls (SSWs) to investigate their seismic behavior. The results of conducted pushover analyses showed that more plastic hinges were created in the CSSW-equipped frames than SSW-equipped ones, indicating more energy absorption, fewer damages and more durability.
