Abstract :
This study presents the seismic analysis and design of a G+6 reinforced cement concrete (RCC) commercial building located in Amaravati, Andhra Pradesh, which falls under Seismic Zone III. The structural modelling and analysis are carried out using ETABS software by considering dead load, live load, and seismic loads in accordance with IS 1893 (Part 1): 2016 and IS 456:2000. The Response Spectrum Method is adopted to evaluate the dynamic response of the structure. The maximum storey displacement under dead load is observed as 6.1 mm in the X-direction and 4.42 mm in the Y-direction, while under live load the corresponding values are 4.006 mm and 3.579 mm, respectively. For seismic loading, the maximum storey displacement under RSX is 0.094 mm in X-direction and 0.100 mm in Y-direction, whereas under RSY it is 0.078 mm and 0.153 mm, respectively. The computed storey drift values for all load cases are found to be within the permissible limits specified by IS 1893 (Part 1): 2016. The maximum base shear occurs for load combinations 1.5 (DL + RSX) and 1.2 (DL + LL + RSY). The fundamental natural time period is obtained as 2.343 seconds in Mode 1. The overall bending moment and shear force values are within acceptable limits, indicating satisfactory structural behavior. Based on the analysis results, the G+6 RCC commercial building is structurally safe and stable under seismic loading conditions.
