Abstract:

© 2019 Elsevier Ltd The single-layer reticulated dome is common in public structures, which suggests that this kind of building is a potential target of a terrorist attack. Once this structure is severely damaged in a terrorist attack, the people inside could be seriously injured. To avoid this situation, it is of great significance to investigate the failure mechanisms of the single-layer reticulated domes subjected to blast. In addition, shock waves from a blast converge and propagate in the internal space, leading to a nonuniform blast pressure field on the inner surface of the dome. The effects of reflected waves on failure modes of the dome were systematically investigated. A finite element model of a reticulated dome was created using ANSYS/LS-DYNA, where the code for blast loading that accounted for wave reflection was incorporated. Five failure modes were recognized and defined from 1050 simulations. Regularities in the distributions of failure modes were found. The effects of reflected waves on failure modes were analysed quantificationally.
