Reliability Analysis of Structures under Blast Loading
Amin Gholizad , Elham Abedi
Abstract:   (1576 Views)

A probability based assessment procedure has been proposed in this study aiming to take into account the stochastic nature of explosive loading and different blast scenarios. It is first necessary to identify the structure behavior against the explosions and probabilistic assessment of responses considering the structural and loading uncertainties. A reinforced concrete building has been considered to evaluate the efficiency of proposed approach in this study. The ANSYS Autodyn Ver.14 software has been utilized for modeling and analysis under blast loading and the damage level of structure has been specified using the pressure-impulse diagrams and the structural fragility curves dependent on the explosive weight and scaled distance have been utilized to evaluate the structural reliability.  The sensitivity of the probability of structural failure respect to the uncertainty parameters of blast loading indicates that the uncertainty parameters related to the blast loading are more important in comparison with the uncertainties in structural characteristics. In general, the reliability analysis of the existing buildings can be an appropriate way to decide for repairing or renovating of the structure.
