COLLAPSE ANALYSIS OF STEEL FRAME WITH CONCRETE FILLED STEEL TUBE COLUMNS
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
This paper present seismic performance assessment of steel frame consisting of CFST column, according to the procedure provided in FEMA P-58, evaluation of building response and estimating median value of structural response parameters in terms of story drift and story acceleration were carried out. To exactly predict the response, 5-Story and 10-Story buildings are used. In this research paper the response of steel frame with CFST column at failure is obtained by performing a series of non-linear analysis, firstly non-linear static analyses is used to check the yielding and failure roof displacement then incremental dynamic loading is used. IDA is performed with increasing intensities until the collapse is occur then the response of building in terms of storey drift and displacement is obtained. The results obtain show that with vertical irregularities the drift and displacement of building increases and special care should be taken when building built with CFST column is subjected to any vertical irregularities
