Analysis of Steel Buildings with Steel Plate Shear Walls at the Corners with Varying Thickness

Abstract

Nowadays the construction of steel buildings is very common. When a building's height increases, its stability is taken into account. Shear walls have to be added to these structures for them to endure the lateral loads caused by wind and seismic activity. Steel plate shear walls (SPSW), one of the shear wall types, are the most efficient since they are lighter and thinner, enhancing the architectural space and rigidity of the structures. This study employs ETABS software to display the seismic analysis of a 15-story steel structure in seismic zone III that has steel plate shear walls at the corners and centre. This article also compares the performance of another 15-story steel building with steel plate shear walls of different thicknesses (15mm, 20mm, and 25mm). The steel building with the thicker steel plate shear walls at the corners performs better in terms of storey displacement and storey drift when compared to other structures. According to IS 1893:2016, the models are examined using the response spectrum method.
