Abstract

In this paper, an approach to identify the potential of progressive collapse is presented. This uses the distribution of strain energy before and after a damage event. The initial damage is modeled through the loss of a column. Numerical examples are presented to predict the progression of damage under gravity loads. The results show that the gain in initial strain energy density for individual elements following some damage can reasonably predict how the damage might spread further. This can help take appropriate measures at an early design stage.
