Numerical Analysis for Progressive Collapse of a Multi-Storey Building due to an Explosion in its Basement
A numerical analysis for the progressive collapse of a reinforced concrete frame caused by an explosion in this structure’s basement is presented in this paper. The whole process from the detonation of the explosive charge to the complete demolition is reproduced. The main work is focused on the role of soil in structural collapse and failure mode of structural members. The analysis is simulated using ANSYS/LS-DYNA and proposes a new simulation method which is comparatively accurate and economic.
