Progressive Collapse of Flat Slab Buildings

Progressive collapse occurs when a local failure triggers successive failures leading to total collapse of the structure. In this project, progressive collapse analysis has been done using a finite element linear static and a non linear static analysis on a 6 storey flat slab building. Though there are dynamic methods also for the analysis but static method has been used owing to its practicality and simplicity in engineering world. Dynamic method is more complicated and involves a number of iteration before it can give any close to accurate result, hence is not in much demand nowadays. The results for the linear static analysis have been compiled in the form of demand capacity ratio at critical section and results for that of the non-linear static analysis have been compiled in the form of support rotation at joints. In both the case the building is not susceptible to progressive collapse both when the central column is removed and the corner column is removed.
