Title: Nonlinear Dynamic Analysis of Reinforced Concrete Slabs Under Impulsive Loads

Abstract:A triaxial failure criterion is applied together with the theory of plasticity for modeling concrete in reinforced concrete slabs subjected to impulsive loads. The transverse shear stresses are extrapolated and then included into the dynamic layered finite element procedure, as it is assumed to affect not only the ultimate behaviors but also the failure modes. A provision for material nonlinearity cracking in concrete elements, and the loading and unloading phenomena are adopted in this study. Verification of the analytical procedure is carried out by means of comparisons with test results on full-scale reinforced concrete slabs. The ultimate behaviors, post-failure behaviors, and the failure modes can be predicted accurately using the proposed procedure. The procedure could serve as a tool for a dynamic design method for concrete slab structures subject to impulsive loads.
