Abstract :
A numerical investigation has been carried out to examine the behavior of reinforced concrete slabs subjected to uniform blast loading. The aim of this work is to determine the effects of various parameters on the results. Finite element simulations were performed in the non linear dynamic range using an elasto-plastic damage model. The main parameters considered are: the negative phase of blast loading, time duration, equivalent weight of TNT, stand-off distance of the explosive, and slab dimensions. Numerical modeling has been performed using ABAQUS/Explicit. The results obtained in terms of displacements and propagation of damage show that the above parameters influence considerably the nonlinear dynamic behavior of reinforced concrete slabs under uniform blast loading.
