Resistance Analysis of RC Frame Corner Joint Subjected to Progressive Collapse

Peng Zhang, Zhi Yong Yang, Huan Ting Zhou, Jun Hu

Abstract

The corner joints of the fringe frame are the most vulnerable components among RC frame structural joints when subjected to progressive collapse, but very few research focused on its performance against progressive collapse. In this research, nonlinear static analysis method was used to analyze the vertical resistance of corner joint against progressive collapse by finite element software ANSYS. The influence of structural design parameters were also studied through comparative analysis. The result shows the joint ultimate vertical resistance is mainly influenced by the moment carrying capacity of the beam ends and column ends. Consequently, this research could offer reference for structural design against progressive collapse.
