Abstract : This paper describes the problem of structural failure (collapse) as a result of a multiple blast load condition. Due to the non-deterministic nature of the problem, the method described herein considers the failure probability of the structure after each blast. The structure is modeled as a single degree of freedom dynamic system with a resistance function which provides for degradation of strength. The method considers uncertainties in both structural and blast load parameters. Probability of structural collapse is determined for a series of attack conditions separated in time for which the ratio of blast load to resistance of the structure is greater than 1.0. Practical applications of the approach are illustrated along with further recommended applications.
