Simplified progressive collapse simulation of RC frame–wall structures

Abstract A macromodel-based approach to enable post-event progressive collapse analysis of reinforced concrete (RC) frame–wall structures is investigated. A simplified shear wall model is developed to simulate the inelastic behavior of a multi-story frame–wall system due to the sudden loss of a significant portion of the shear wall at the first story. Detailed finite element analyses are employed not only to provide modeling insights but also as a tool to verify the accuracy of the developed shear wall model. Two perimeter frame–wall systems designed for different seismic zones are modeled using the proposed approach and numerical simulations following the sudden loss of a portion of the shear wall at the lowest story are compared and evaluated. Although no signs of collapse are evident in either system, detailed investigation of force variations in structural members shows that the seismically designed frame–wall system (SDC-D) is a more robust system compared to a system designed for much lower seismic demands due to the effectiveness of its structural layout and seismic detailing. The simplified methodology is a suitable approach for preliminary progressive collapse investigation of RC frame–wall structures.
