Title: Challenges of FEA Modeling the Performance of Concrete Substructures under Blast Loading

Abstract:Successful modeling of the performance of concrete substructures under blast loading requires an understanding of the limits of the material model and a reasonable bounding of the anticipated results. This paper presents a case study of a prestressed bridge double tee section under both near and far range threats. A conventional SDOF analysis was employed to bound the anticipated structural response. In addition, finite element analysis was conducted in LS-DYNA utilizing three different constitutive material models for the concrete under the two loading conditions. Determining the accuracy of the finite element analysis results was found to be challenging due to the wide range of responses corresponding to the respective material models.
