Response Spectrum Analysis of A G+3 Building With Wind Loads

This article conducts a Response Spectrum Analysis (RSA) of a G+3 reinforced concrete framed structure utilizing STAAD Pro. The natural frequencies for the initial three vibration modes, total base shear, inter-story drift ratios, and roof-level displacement are extracted and analyzed. The RSA is performed in accordance with IS 1893:2016 (Part 1) for Seismic Zone V, utilizing medium soil, an importance factor of 1.0, a response reduction factor of 5.0, 5% damping, and CQC combination methodology. The findings indicate that the initial three natural frequencies are 2.933 Hz, 5.056 Hz, and 9.372 Hz, the cumulative base shear is 243.86 kN, and the maximum roof displacement is 4.050 mm. These values offer insight into the building's dynamic performance.
