Abstract:
Numerical simulations of Reinforced Concrete (RC) panels subjected to blast loads are presented in this paper. In spite of a large number of events such as explosions and bombings in recent years, there is a difficulty in accurately predicting the behavior of structural systems due to blast loading. The effects of blast loads on 64” (L) x 33.75” (W) x 4” (H) RC slabs are studied using both nonlinear finite element analysis and Single Degree of Freedom (SDOF) models, and the analysis results are compared with available test results provided by the University of Missouri-Kansas City. This study investigated the gap between actual and predicted response of reinforced concrete structures subjected to highly dynamic loading such as blast. The effects of concrete strength, reinforcing steel grade, and the magnitude of blast loads on the dynamic response of reinforced concrete panels are considered.
