- Progressive collapse has attracted more and more attention due to the happened extreme events. The static pushdown method is widely used to analyze the progressive collapse capacity of RC structures. However, the previous research hardly takes the random variables (e.g., geometric dimension and material properties) into consideration. This paper develops a reliability analysis framework for RC structures subjected to different column removal scenarios. In the framework, an efficient deterministic model is firstly developed based on the fiber element in software OpenSEES. Then a reliability analysis method is proposed based on the probability density evolution method (PEDM). Two typical RC frames are designed and tested by the reliability analysis method. The results show that the reliability analysis framework works well on the two designed RC frames.
