Abstract - Seismic forces play a crucial role in the design and performance of multi-storey buildings in earthquake-prone regions. This study presents a comparative analysis of a G+14 reinforced concrete building located in Surat (Seismic Zone III as per IS 1893:2016). The structural model is developed in ETABS and analyzed using Equivalent Static Method, Response Spectrum Method, and Time History Analysis based on Bhuj earthquake (26-01-2001---7.7 magnitude) and Burma earthquake (06-08-1988---7.5 magnitude) records. Key response parameters such as base shear, storey displacement, storey drift, and overturning moment are evaluated and compared across all methods. The study highlights variations in structural response and provides insights into the suitability of different seismic analysis techniques for buildings in seismic zones III.

Key Words:  Seismic Analysis, G+14 Reinforced Concrete Building, Equivalent Static Method, Response Spectrum Method, Time History Analysis, Bhuj Earthquake Record, Burma Earthquake Record, ETABS, Seismic Zone III, Storey Drift, Displacement, Overturning moment, Base Shear.
