The seismic safety of multi-storeyed reinforced concrete buildings is a critical concern in earthquake-prone urban India. This study presents an exhaustive comparative analysis of a G+10 RCC frame subjected to static and dynamic seismic loading, employing Equivalent Static Analysis (ESA) and Response Spectrum Analysis (RSA) methods as prescribed by IS 1893:2002. The model, created in ETABS, features 600×600 mm columns and 600×450 mm beams, with loads and codal factors rigorously assigned. Results reveal that RSA better captures higher mode effects, torsional irregularities, and realistic forces and deformations, whereas ESA provides only an approximate, conservative overview. Quantitative findings across story shear, displacement, drift, and modal participation establish RSA as essential for medium- and high-rise structures, enhancing both safety and economy. This article serves as a technical blueprint for codal-compliant seismic design and research publication.
