The collapsed of any building is due to the loss of one or a few structural components which then progresses over the
successive other components. This process is called as progressive collapse of the structure. Progressive collapse is the process of
extensive failure initiated by local structural damage, or a chain reaction of failures. Local damage that initiates progressive
collapse is called initiating damage. Progressive collapse can be triggered by many different actions and the prediction of such
abnormal actions is very difficult and depends on many factors Hence, there occurs the loss in load-carrying capacity of the
small portion of a structure due to abnormal or haphazard load which progresses in series of failures of other components and
thus the collapse of the building take place. Therefore, a typical analysis approach for determining robustness against the local
failure and accidental occurrences for a RC framed structure has been attempted in this study to evaluate the demand capacity
ratio
