Impact Of Plan Irregularities On Performance Of Building Subjected To Seismic Load

Abstract

The present study, investigates the impact of different types of plan irregularities on the building subjected to seismic force. The L, H, T, U Shaped plan irregular building are moderate in ETABS software, then seismic load along with gravity load is assigned as per IS codes. The equivalent static method is used for analysis. The study confirms that plan irregularities play a critical role in determining seismic performance, and among the studied configurations, the T-shaped structure shows the most suitable for resisting earthquake-induced forces. These results provide valuable insights for engineers and designers in optimizing irregular building layouts for both functionality and resilience.
