Static, Dynamic and Pogressive Collapse Analysis of Multi Storey (G+10) Residential Building by ETABS Software

Abstract

This project presents an attempt to do static, dynamic and progressive collapse analysis of multistory (G+10) residential building by ETABS (Extended 3D Analysis of Building Systems). ETABS is software that helps to anatomization and design of low and high-rise buildings and frame structures. In this project G+10 RC frame building is analysis statically (linear method) and dynamically (Response Spectrum method) along with Progressive Collapse analysis. All the members of the project are analyzed as per Indian codes IS 456:2000, IS 800:2007, and IS 1893:2002 (part1) code using this software. Here the result for Story stiffness, Base shear, Story Shear, Overturning moments, Maximum displacement, and Story Drift is compared between static and dynamic results for Zone2-(case1), Zone3-(case2), Zone4-(case3), Zone5-(case4) with medium soil type and for Progressive Collapse analysis GSA guidelines are followed. As per GSA guidelines three column removal cases for each case1, case2, case3, and case4 individually studied, namely Corner column removal, Exterior column removal and interior column removal at ground floor. For all three cases linear analysis study has been undertaken and DCR ratios are evaluated. Member having DCR ratio greater than 2 will going to fail for corresponding column removal case.
