Progressive collapse arises when local failure in a building member spreads to the adjacent members, this may promote further failure. In general, structures are designed to bear the normal expected loads like dead load, live load and lateral load (wind and seismic). However, some structures rarely are being exposed to sudden loads due to natural, man-made, intentional or unintentional reasons. These unexpected loads induce progressive collapse event. Therefore, many studies have been conducted to improve the building performance against extreme load hazards and progressive collapse phenomenon. In this work various position of GF column is selected and removed floor wise. As a result, the prime objective of this study is to find out the most critical location of the removed vertical-support element. Additionally, Linear static analysis of the three-dimensional (3-D) computer models of each selected building was carried out by using STAAD. Pro program. Ultimately, observations from this research demonstrate that the increase in the height of the structure and the removal of column from the bottom or near the bottom of the short side of the building is more significant to progressive collapse event.
