Abstract |
Progressive collapse occurs when a primary structural component fails which results in the failure of adjacent components which in turn causes complete failure of structure. It might be man-made or natural hazards. In the present study the behavior of RC 12 storey RC frame structure are designed and evaluated as per U. S. General Services Administrative (GSA) guidelines. Structure considered consists of irregular geometry with a typical structural configuration of L-shaped block. Bay size is taken as 4m in X-direction and 3.5m in Y-direction and height of each storey is 3.6m. Progressive collapse was carried out using Linear Static Analysis in E-TABS version 13 software. The behavior of bending moment and axial forces variation are studied for the single column removal. It involves two case study i.e., exterior and interior column removal. It was observed that when exterior column was removed in the structure most of longitudinal beams and floors above the column will collapse. When ground floor interior column was removed there was no effect on the beams and floors and when upper floor interior column was removed the effect was observed on beams in short span. |
