Dynamic Response Analysis of the Reinforced Concrete Column under the Effect of Explosive Impact Load

摘要

This paper does the data simulation analysis by using the large-scale finite element nonlinear ANSYS/LS-DYNA software. It chooses the MAT111(MAT-JOHNSON-HOLMQUIST -CONCRETE)concrete materials and the MAT3 (MAT-PLASTIC-KINEMATIC) reinforcement material model in ANSYS/LS-DYNA finite element software, builds the separating RC column finite element model, dynamically simulates the hurting process of RC column under the effect of explosive impact load, and mainly does research into the damage degree of RC column under different effects of explosive load of different peak pressures.
