Abstract

Under blast load, the progressive collapse performance of reinforced concrete structures is very complex. This article gives a more applicative and efficient RC frame structure model by ANSYS/LS-DYNA, and studies the effects of concrete strength and longitudinal reinforcement ratio to progressive collapse performance by parametric analysis, then calculates the critical load and dynamic amplification factor. It is found that the progressive collapse resistant capacity can improve with the concrete strength and longitudinal reinforcement ratio, the critical load of the frame structure is 3.15 times of the design load, and the dynamic amplification factor is 1.32.
