Title

Investigation the effects of HPFRCC materials on the robustness of RC frames subjected to progressive collapse

Pages

  258-279

Abstract

 The Beam-Column joints play a key role in maintaining the stability of Reinforced concrete structures against Progressive collapse, and proper design of Beam-Column joints prevents sudden collapse of the structure. Fiber reinforcement cementitious composite materials (HPFRCC) with strain hardening behavior under tensile loads are a new alternative to conventional concrete. In this study, the effects of using HPFRCC in the Beam-Column joints on the robustness of concrete structures against Progressive collapse have been investigated. For this purpose, after verifying the simulations with experimental results using OpenSees software, the performance of two 10-story Reinforced concrete structures against Progressive collapse has been studied. The robustness of the studied structures has been measured using the Robustness index proposed by Fascetti et al., which is one of the most comprehensive and reliable methods available for evaluating the robustness of concrete structures. The results of analysis show that the use of HPFRCC materials in the beam-column joint can increase the robustness of the structure against Progressive collapse by increasing the strength and ductility of the structure. It was also observed that the use of HPFRCC materials in the Beam-Column joints increases the nonlinear dynamic and static Robustness index of the structure by 25. 22% and 58. 32%, respectively, compared to the structure with conventional concrete joints.
