Progressive Collapse Analysis of Masonry Infill RCC Structures
The Masonry infills in RCC structures have become quite common in construction however their effect of initial stiffness is not considered generally. The adversity or the potential of progressive collapse can be studied only by considering the effect of infills in the structure. During the collapse of a structure, the properties of infills also affect the potential or gravity of collapse. In this study a G + 8 storey structure with cellular light weight concrete masonry block were modelled as diagonal strut by equivalent diagonal strut approach in order to consider the effect of masonry infill in the structure. By GSA guidelines columns susceptible to more damage were removed. The critical columns were assessed by demand capacity ratio by P-M curve. By P-M interaction curve the structure with corner column removal and short side column scenario exhibited more critical columns.The critical column in the structure were removed and assessed by displacement coefficient method of Push over analysis in FEM software ETABS. The total energy capacity of short side column removal structure was found to be 21% greater than corner column removal structure and the effect of damage of corner column removal structure were much higher than the short end column removal structure.
