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

Abstract
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.

Highlighs
- The seismic behavior of 3, 8 and 15-floor frames equipped with composite steel shear walls (CSSW) and conventional steel shear walls (SSW) was analyzed by pushover analysis.
- To this end, triangular template lateral loading was applied to the numerical models, and the plastic hinges of beams, columns and diagonal steel strips were obtained.
- The diagonal steel strips went to the plastic region before the surrounding beams and columns in all numerical models.
