Seismic Response of Plan Regular G+15 RC Structure and Analysis of Structure by ETABS

Jul 2026 · International Journal for Research in Applied Science and Engineering Technology · Vol 14, pp. 2405-2413 · 0 citations

Abstract

The present study evaluates the seismic performance of a G+15 reinforced concrete (RC) framed building using ETABS software in accordance with IS 1893 (Part 1): 2016. The building is modelled as a plan-regular structure located in Seismic Zone V with medium soil conditions. Modal Analysis, Equivalent Static Analysis, and Response Spectrum Analysis are carried out to assess the dynamic behaviour of the structure under earthquake loading. Important structural parameters such as natural time period, modal participation ratio, base shear, storey displacement, and storey drift are obtained and analysed. The results indicate that seismic response varies significantly along the height of the building, with maximum displacement and drift occurring at the upper storeys while remaining within the codal limits. The study demonstrates that ETABS is an effective tool for evaluating the seismic behaviour of multi-storey RC buildings and provides valuable information for designing safe and earthquake-resistant structures.
