The Effects of Bracing on the Behavior of RC Multi-Story Frames to Resist Progressive Collapse
Steel bracing has proven to be one of the effective methods to upgrade lateral load resistance of reinforced concrete (RC) frames. However, little studies had been carried out on the efficiency of steel bracing for improving the behavior of RC frames in resisting progressive collapse. In this paper, the effects of steel bracing on the behavior of RC frames in mitigating progressive collapse are investigated experimentally. One bare frame without bracing and two braced frames with additional steel bracing in the third floor are tested. It is found that steel braces could increase the first peak load up by 126.9 % while the braces has little effects on the catenary action in large deformation stages. In general, the eccentric bracing system is performed better than the concentric one.
