Explosion phenomenon has been most attractive subject for researchers during different era, from innovation of gunpowder to these days. The biggest of these researchers has been done during WW2. At last years, many terrorist attacks have been done by using explosion materials and bombs. Explosion is a chemical reaction; it finishes in some mill-second. During reaction a huge amount of energy release in the atmosphere and cause a pressure wave by high speed. Wave attacks building, impacts and forces them. In general, RC buildings have better reaction to explosion wave, because of their high mass. In this study, main goal is to observe the RC building under explosion load and finding ways to reduce or prevent damages. To model the RC building the ABAQUS Finite Element software has been used. For modeling it has been tried to make the model very close to the reality and to cover the proper details. The results show that distance has significant effect on reducing the explosion wave pressure and consequently on applied explosion loading.
