Abstract

In order to investigate the effects of strain rate on nonlinear seismic disaster process of RC structures under earthquake,using the uniaxial dynamic constitutive relations of reinforcement and concrete and their loading and unloading regulations,a material subroutine of ABAQUS explicit dynamic analysis based on the fiber beam theory was developed. Numerical simulation with this subroutine for a three-story RC frame-shear wall structure’s shaking table test was conducted to verify the correctness and effectiveness of this subroutine applied in RC structures’nonlinear seismic response analysis. The simulation for progressive collapse damage process of a RC structure considering strain rate effect was realized by defining failure damage criteria of reinforcement and concrete in the material subroutine. The progressive collapse damage modes of the shaking table test’s model structure and the RC frame structure were predicted,respectively. The effects of strain rate on the seismic response and progressive collapse damage process of the RC structure were preliminarily discussed. The results showed that the developed subroutine can correctly simulate the nonlinear seismic disaster process of RC structures,and it can be applied in RC structures’aseismic design and analysis considering strain rate effect.
