Modelling the dynamic response and failure modes of reinforced concrete structures subjected to blast and impact loading

摘要: Responding to the threat of terrorist attacks around world, numerous studies have been conducted search for new methods vulnerability assessment and protective technologies critical infrastructure under extreme bomb blasts or high velocity impacts. In this paper, a two-dimensional behavioral rate dependent lattice model (RDLM) capable analyzing reinforced concrete members subjected blast impact loading is presented. The inherently takes into account several major influencing factors: progressive cracking in tension, inelastic response compression, the yielding reinforcing steel, strain sensitivity both steel. A computer code using explicit algorithm was developed based on proposed model. along with numerical validated experimental test results from Woomera trial.
