The demand for the construction of multi-story buildings is increasing rapidly due to growing competition and the need for more economical and spacious buildings. Theoretical calculations for such structures are critical and there is a growing demand for fast software to speed up the process. This dissertation uses computer program such as ETABS to design and analyze a multi-story building in two forms i.e. R.C.C and Composite Structure. The Indian design code is used for the design and the structure analyzed is an R.C.C and Composite Structure with 10 story and 15 stores. The seismic performance of structures is a critical factor in designing and constructing buildings in seismic-prone regions. This dissertation presents a comparative study of the seismic resistance of Composite and Reinforced Concrete (RCC) structures under different soil conditions (Rock or Hard soil, Medium soil, Soft soil) and seismic zones (II-Nagpur, III-Pune, IV-Delhi, V-Srinagar) using the ETABS software. The project evaluates the performance of composite and RCC structures in terms of lateral deflection, story drift, and base shear values and compares their response using the Response Spectrum Method and Time History Method. The study investigates the effects of different seismic zones (II-Nagpur, III-Pune, IV-Delhi, and V- Srinagar) and soil conditions (Rock or Hard soil, Medium soil, Soft soil) on the seismic resistance of these structures. The design of the structure follows the Indian design code, which includes the following codes: IS 456:2000, IS Code 800, IS Code 1893:1984, and IS Code 11384:1985 and so on. Composite structures are found to be the best mode of construction for high-rise building while comparing with the conventional R.C.C structures as they serve well for various parameters like lateral deflection, story drift and base shear values. The findings of this study can assist in selecting the most efficient and reliable type of structure for seismic resistance in different seismic zones and soil conditions.
