Abstract

Reinforced concrete (RC) is the most widely used construction system in construction. The non-linear response of concrete when subjected to extreme dynamic loads such as blast is an important consideration for analysis and design of structures members. In this paper numerical modeling of RC column under blast load is presented using LS DYNA explicit dynamics software package. The accuracy of the model to simulate RC column responses to blast loads is verified by comparing the numerical simulation results with the test results available in the literature. A parametric study was chosen to investigate the effects of charge weight and stand-off distance on the dynamic behavior of RC column. The results of the numerical study show that the charge weight and standoff distance has a significant effect on the behavior of RC columns under explosion loading.
