Progressive collapse analysis of seismically designed three-dimensional special moment resisting frames
U.S. General Service Administration (GSA), 2013 guideline was used in the progressive collapse analysis of seismically designed three-dimensional special moment resisting frames. The analysis was carried out to assess the vulnerability of low, mid and high-rise three-dimensional special moment resisting frames with six bays in either direction. All the structures considered for this study were designed according to the Indian Standard codes. To evaluate the behavior of the structure, linear static analysis (LSA), non-linear static analysis (NLSA), linear dynamic analysis (LDA) and non-linear dynamic analysis (NLDA) have been carried out by using Alternate Path Method (APM) for column removal at the critical locations based on these guidelines. The results show negligible displacement versus time history when compared between LDA and NLDA. It also reveals that the removal of the internal column leads to less vibration when compared to the other two locations during sudden removal. From the analysis results it is also observed that the height of the structure is largely affect the behavior of the structure during sudden removal any column.
