Abstract

In this study, in order to establish a damage evaluation method of RC structures subjected to contact detonation loads with numerical simulation, three-dimensional elasto-plastic impact analyses based on Finite Difference Method (F.D.M.) were carried out on RC slab models. The numerical results were discussed on sizes of crater and spall, cracking on the slab surfaces and reinforcement strain, compared with experimental results. The main results obtained are as follows: 1) The numerical results are relatively in good agreement with experimental results for the diameter and depth of spall, and the depth of crater. 2) Cracking on the top surface of the slab is almost simulated, and numerical cracking on the back surface is similar to experimental one. 3) Strain level is well predicted with the numerical simulation.
