Abstract
This project work presents the progressive collapse analysis of low rise mid-rise and High rise RCC building for blast load. In structure due to the spread of local damage form one part to another part or proportionately big part of the structure gets collapsed in progressive collapse. Progressive collapse analysis is performed on low rise for G+4, medium rise for G+17 and high rise for G+22 building and its validation in accordance with General Services Administration 2013 Guidelines, to check Demand Capacity Ratio of a respective structure. The response of RCC framed structure under blast and seismic loading is checked in this work. Regular framed structures of G+4, G+17, G+22 is designed and analyzed using STAAD-PRO V8i SS5. Time history analysis method is used for progressive collapse analysis. Columns are removed to initiate the progressive collapse. for blast analysis time history load is calculated as per IS 4991.Natural frequency, storey drift, base shear, vertical displacement before and after column removal are calculated and Demand Capacity ratio is checked. The obtained DCR values shows that columns are safe for low rise (DCR is 1.5), Medium rise (DCR IS 1.6) and high rise building (DCR is1.9) DCR within the acceptance criteria.
Keywords: Progressive collapse, demand capacity ratio, column removal, blast load, STAAD pro
