This study proposed an evaluating method of the risk of a RC structure when explosive incidents occured. As a hazard curve, the relationship between explosive quantity and frequency of the explosive incident was evaluated based on the statistics of terrorist's bombings in the world. In order to evaluate a fragility curve based on calculation of dynamic response, members of the RC structure, i.e. beam, column, slab, window, were modeled as a single degree of freedom model. Total probability of failure of the RC structure was estimated by superposing the fragility curve of the members. Losses of the RC building and people were calculated based on the damage states of the RC building. A risk curve was evaluated based on the hazard and loss curves.
