Pogressive Collapse Analysis of Multi Storey (G+10) Building by Staad Pro. using Column Removal

Abstract

This project presents an attempt to do progressive collapse analysis of multistory (G+10) residential building by STAAD Pro (Structural Analysis and Design Software Application). STAAD Pro is software that helps to analysis and design of low and high-rise buildings and portal frame structures. In this project G+10 RC frame building is analysis statically (linear method) along with Progressive Collapse analysis. In progressive collapse the weight of the building transfers to the neighbour columns in the structure causes to the failure of adjoining members and finally to the failure of partial or whole structure. 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 is compared between the shear force, bending moment variations value of corner column, Zone1, Zone2, Zone 3 by STAAD Pro. 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 one at a time has studied, namely Corner column removal, Exterior column removal and interior column removal all at ground floor.
