Abstract
A batch of blast resistance reinforced concrete slabs were tested in the shock tube facility at the University of Missouri Kansas City (UMKC). Based on the results from the tests, a blind numerical simulation contest was announced by UMKC in collaboration with the American Concrete Institute (ACI). The authors of this paper participated in the contest and received the test results only after completing their simulations. In this paper two basic numerical approaches are described. The first is a preliminary section rigidity assessment and the second is a full numerical simulation performed with the LS-DYNA code. The numerical results are compared with the UMKC test results and the influence of the numerical parameters is further discussed. The section rigidity assessment approach is then used to explain some unexpected results.
