Progressive Collapse Analysis of RC Multi-Story Building

The term “progressive collapse� is the spread of local failure from an element to other element within the structure ultimately causing total collapse of the build-ing. It is caused due to abnormal loading being induced in the building. The abnormal loading may be induced by earthquake, bomb blasting, tsunami, aircraft impact, any other man-made intentional or unintentional activi-ties and other natural hazards. These loadings causes change in the loading pattern and boundary condition of the structure, this result in other structural elements within the structure to load beyond their capacity and fail. Thus the failed structure is required to seek alternate load path in order to redistribute its load. This process continues until the structure finds the equilibrium by element failing or by finding alternate load path to dis-tribute the load. In this project a multi-story building designed, using IS codes is considered for progressive collapse analysis. Linear static analysis is carried out by using ETABS as per GSA guidelines. Story shear and story drift are calculated to know the potential for progressive collapse.
