Finite Element Modeling of RC Beam Column Sub-assemblages Subjected to Column Loss Scenario
Abstract: Progressive collapse is a situation where a failure of whole or large part of a structure occurs that has been initiated by failure of a relatively small part of the structure such as failure of any primary structural element. When a vertical load carrying element, typically a column is lost, the loads that are supposed to pass through lost column need to be safely transferred to the adjacent elements to …
