Failure Analysis of Reinforced Concrete Beams Subjected to Explosion and Post-Explosion Fire

Abstract:

In order to investigate deformation and failure of reinforced concrete beams subjected to combined actions of explosion and post-explosion fire, A three-dimensional numerical approach was developed with finite element software ABAQUS. And the numerical approach consists of three steps: quasi-static analysis, explicit dynamic analysis and sequentially coupled thermal stress analysis. The rate-sensitivity and temperature property of material were included in the constitutive model, Fire resistance of reinforced concrete beams subjected to explosion and post-explosion fire was investigated by the method quantificationally. It is demonstrated that fire resistance of reinforced concrete beams is reduced by the action of explosion.
