Özet

Progressive collapse is defined as the spread of an initial local failure of a structure. This phenomenon, caused by the removal of one or more load-bearing elements, is followed by a chain of failures through the structure and ultimately leads to partial or even full collapse of an entire structure. As a result, an accurate understanding of structural behavior subjected to large displacements, caused by progressive collapse, is essential to ensure a safe structural design. In this study, the behavior of the beam-column assembly subjected to progressive collapse was investigated by using finite element software. The results were compared to those of the results published in the literature, and model validation was ensured. The progressive collapse resistance mechanisms in RC beam-column assembly as well as the effectiveness of each mechanism in progressive collapse prevention were investigated. According to the results, the four resistance mechanisms, i.e., flexural action, compressive arch action, plastic hinge formation, and catenary action, have a significant effect on structural behavior.
