Abstract

Abstract

In order to accurately and efficiently simulate the blasting demolition project, a simplified constitutive model of reinforced concrete has been proposed by using the method of combination modulus, based on the concrete damage plasticity model in LS-DYNA. In the model, we have taken the tension stiffening effect, the ratio of reinforcement effect on tension stiffening, and the confinement effect of stirrups of reinforced concrete into account. On the basis of experimental verification, the numerical calculation has been performed to simulate the delay blasting demolition of a double incision reinforced concrete chimney. The simulated results show that the proposed model can qualitatively reproduce the collapse and movement processes of chimney.
