【 摘 要 】

Center column removal and side column removal scenarios are the two typical research conditions in the investigation of progressive collapse of RC frame structures. The study provides insight into the comparison of progressive collapse performance between center column removal and side column removal scenarios based on experimental results, numerical investigation and theoretical analysis. Based on the difference of progressive collapse failure modes of two frame models, their collapse resistance mechanisms are analyzed, and the different collapse resistance models are proposed. And the comparison between two frame models on the experimental collapse resistances is presented, which is in good agreement with the proposed collapse resistance models. The research results can establish a foundation for progressive collapse analysis and assessment of RC frame structures.
