India faces potential risks for multi-storeyed office buildings in seismically active regions, with over 65% of the country prone to moderate to high intensity earthquakes. Mega cities in these regions are designed for gravity loads only, and earthquake motion causes both horizontal and vertical ground motions. Vertical ground motion has smaller magnitudes, but can be resisted by safety factors in structure design. Structures designed for gravity loads cannot resist horizontal ground motion, which causes significant damage to the foundation by shaking the foundation. Building mass resists this motion by setting up inertia forces throughout the structure. Therefore, it is crucial to check the adequacy of structures to withstand horizontal ground motion, even if it is expensive. The Bhuj Earthquake in 2001 sparked increased awareness of earthquakes' damaging effects in India. The need to evaluate the seismic adequacy of existing buildings has become crucial, especially after the loss of life and property. Seismic analysis is essential for determining the magnitude of lateral earthquake forces, making multi-storeyed office buildings in India a major concern. The objective of the project is to carry out the seismic analysis and comparison of a five storey, ten storey and fifteen storey office building located in zone -III for obtaining the basic parameters like time period frequency storey shears and displacements and compare the result by using the code IS 1893-2016.The analysis of frame is worked out manually and it verified by using ETABS software.
