Analysing the Effect of Structural Configuration on Earthquake-Induced Response Parameters

The seismic performance of high-rise buildings is significantly influenced by their plan geometry. This study evaluates and compares the structural behaviour of buildings with different plan configurations—Rectangular, L-shaped, H-shaped, and C-shaped—using ETABS software, as per IS 1893:2016 guidelines. Response Spectrum Analysis is conducted to assess the performance under seismic loading conditions. Key parameters such as lateral displacement, story drift, story stiffness, are used for comparison. The results highlight the impact of plan geometry on overall seismic response and identify configurations that demonstrate better structural performance. This research offers useful insights for structural engineers during the conceptual planning and design phase of high-rise buildings in seismic-prone areas
