PERFORMANCE BASED DESIGN OF TALL BUILDINGS

Abstract

Most of the structures designed in the 21st century are based on codes, which follows Forced-Based Design philosophy. The basic intent of the codes is public safety. But there is no information for the losses and interruptions faced by the occupants. Codes focus on designing structures for collapse prevention for design based earthquake. But codes don’t mention the continuity of the operations or non-structural elements damages. Performance based design is a new strategy which is far more detailed focusing on the client specific requirements. In this study a high rise structure is designed following Indian Standards. StructuralTo verify the performance of the structure differnetn types of Pushover Analysis are conducted and the results are compared with the Non-Linear Time Histories (matched with the Indian Response Spectra). Damage states for each member was determined, and nonlinear pushover and time history analysis were carried out using SAP2000 v17.10 to check if story drift ratios meet the ones chosen.
