In heavily populated cities the supply of land is becoming less and value of land is becoming higher. In sight of recognition & less availability of land, tall structures are only solutions for overcoming the issues. A tall structure should be designed to resist the lateral load like Earthquake force within the permissible limits set by Standards. Combination of rigid frame with RC structure get 30 storey as maximum storey and liable to collapse under severe displacement, axial force and moment, if the P-Delta effects doesn't include in analysis and style phase. Because of complexity and low knowledge of P-Delta analyses designers, engineers and architectures are liable to perform Linear Static analysis which can eventually become a reason behind catastrophic collapse of the high-rise. The study has been administrated for 15, 20 and 25 story structure with and without P-delta effect. Our study is predicated on “P-Delta” analysis which includes geometric nonlinearity within the analysis. The study has been performed on structural software ETABS.
