Abstract: Earthquakes are among the most destructive natural hazards, often leading to substantial structural damage, human casualties, and economic disruption. These events are caused by sudden energy release within the Earth's crust, generating seismic waves that impact large geographic regions. Past incidents, such as the 2015 Nepal earthquake, have underscored the importance of seismic-resistant design, especially in vulnerable areas. This study presents a comparative structural performance analysis of high-rise residential buildings (G+20) with constant floor area but varying plan shapes, evaluated using ETABS software. The analysis focuses on four distinct geometric configurations and is conducted as per the seismic design provisions outlined in IS 1893 (Part 1): 2002, considering Zone III conditions specific to the Betul region of India. Key parameters assessed include, Seismic force distribution, Bending moments, Lateral displacements, Construction cost implications The objective is to determine the most efficient plan configuration that offers an optimal balance between structural performance and economic viability under seismic loading. The findings aim to guide architects and engineers in adopting geometry-driven solutions that improve seismic resilience without increasing the building footprint.
