Abstract

The trends and demands of lighter and slenderer high-rise building structures are subjected to p-delta effects, most of the existing high-rise buildings damaged due to the past severe earthquakes. To keep these things into consideration, it is necessary to analyse the structures with some advanced analysis procedures and to develop the new methods of analysis to protect the structures from future severe earthquakes. The objective of this research work is to analyse the structure critically and make them stronger during earthquake and it should result in less damage even during the strong earthquake. In the present work the analysis of G+30 building is being done by adopting the various approach of p-delta analysis. In this research work a symmetrical regular reinforced concrete building frame is analyzed statically and dynamically as per IS 1893:2002 (BIS, 2002). The structure is analysed for seismic zone III and V. Seismic Evaluation is performed on same modal for including P-Delta effects. In the first part, analysis is done without considering the P-Delta effect and in the second part P-Delta effect is considered. The results are compared for Static, Dynamic, and P-Delta analysis.
