Abstract

Abstract

With explosion pressure simulator, blast experiments were carried out to investigate the deformation and damage of concrete (RC) beams. The experimental design and parameters are described in detail. The experimental result shows the failure characteristics of RC beams and the role that rebars act. With LS-DYNA, three-dimensional separated finite element models of RC beams were established to simulate the experiment. The simulation and experimental results are contrasted to investigate the damage mechanism and failure characteristics. The article also figures out the reason of simulation errors. The research provides reference for damage assessment and anti-blast design.
