EVALUATION OF NONLINEAR STATIC PROGRESSIVE

Progressive collapse is a catastrophic structural phenomenon that can occur because of human demolition and natural hazards.The mechanisms that are used in order to create progressive collapse can be immensely impacted by the smallest fraction of failure that may cause a significant deformation in the structural capabilities of the building.EVALUATION OF NONLINEAR STATIC PROGRESSIVEin collapse prevention (CP) performance level for the beam as a limit state. The results show that when c1 is removed in 3 story buildings have high potential of progressive collapse but with increase stories the structure is capable to absorb element loss.EVALUATION OF NONLINEAR STATIC PROGRESSIVE COLLAPSE IN IRREGULAR CONCRETE STRUCTURES EVALUATION OF NONLINEAR STATIC PROGRESSIVEin collapse prevention (CP) performance level for the beam as a limit state.
