Progressive collapse in a structure occurs when structure demise the load carrying capacity to resist the specific demand of earthquake and major structural load carrying members get failed due to sudden change in configuration of structure. Progressive collapse can be triggered by manmade, natural, intentional, or unintentional causes. Fires, explosions, earthquakes, or anything else causing large amounts of stresses and the failure of a structure’s support elements can lead to a progressive collapse failure. Progressive collapse is a complicated dynamic process where the collapsing system redistributes the loads in order to prevent the loss of critical structural members. For this reason beams, columns, and frame connections must be designed in a way to handle the potential redistribution of large loads. Progressive collapse assessment helps to improve the design of structure based on concerned response steel structure under dynamic loading. This research should be provide insight into the structural configuration to achieve a demand to capacity ratio of appropriate quantity and prevent collapse in the event of a single column loss. Several relationships shall be developing between bending moments, shear forces, column loading etc. Ultimately, all this information can be use in design codes where there are currently very limited or no specific rules or guidelines directed towards prevention of progressive collapse.
