Numerical Investigation on Collapse Kinematics of a Reinforced Concrete Structure within a Blasting Process

S. Mattern (Universität Karlsruhe) In the present contribution numerical analyses were performed in order reach a prediction of the collapse kinematics of a real building subjected to blast loading. The collapse process is simulated with a pure finite element model and "validated" by a video sequence of the blasting process. A criterion for substituting several structural parts with rigid bodies is discussed and the resulting simulations are compared with the pure finite element solution. All finite element and so called 'hybrid rigid body' simulations were performed with the parallelized version of LS-DYNA on the HP-XC6000 Cluster at the University of Karlsruhe. These investigations are processed within the research unit FOR 500 "Computer aided destruction of complex structures using controlled explosives" funded by the Deutsche Forschungsgemeinschaft (German Research Foundation).
