Comparative Study between Analytical Models of Steel Plate Shear Wall

Abstract

In the past few decades, the unstiffened steel plate shear wall (SPSW) has proved to be an economical and effective solution for resisting wind and earthquake forces in multi-story steel buildings. In this research, a detailed model, and various simplified models available for unstiffened SPSW are compared. The detailed model represents the actual behavior of the wall when it is subjected to lateral forces. Simplified models are developed based on the formation of tension fields in the steel plate wall after it gets buckled due to in-plane shear stresses. ETABS software is used for the analysis and comparison of these models. Six G+12 steel buildings were modeled for four available simplified models and a detailed model and moment resisting frame with no shear wall. The equivalent static method mentioned in IS 1893-2016 is adopted for Zone III of an earthquake in the analysis and design of steel plate shear walls. Parameters like base shear, storey displacement, and geometric properties of infill plate and boundary elements are compared. Geometric properties of the plate and boundary elements are designed manually using American and Canadian steel design codes i.e., AISC 341-16 and CSA S16-09 respectively.
