Linear Static Analysis For Progressive Collapse Of Steel Structure Under Fire Loads
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 5
Abstract
Progressive collapse is defined as extension of initial collapse, from a part of structure to another one that may result in destruction of steel structure. Possible risks and abnormal loads that causes progressive collapse are as follows aircraft collision, design or construction error, firing, gas explosion etc. Such phenomenons are not consider in designing typical structure, since possibility of occurring these kinds of risks is very low. In this study G+8 steel frame structure was analyses the columns are subjected to different load combination along with fire loadings ranging from 250℃ -1000℃ at an interval of 150℃ for alternate storey’s, selecting the columns are corner, edge, intermediate and re- entrant columns.. Load combinations were adopted as per IS 875 Part I and II. Then the structure is checked for the DEMAND CAPACITY RATIO (DCR) value in terms of linear static analysis for the columns which are obtained and compared with as per GSA guidelines 2016 by using software E-TAB 2015.
