A new type of subroutine VUMAT (tj_fiber) is developed to simulate the mechanical behavior of rebar in reinforced concrete members under cyclic loading. The constitutive model used for tj_fiber was with reference to the adjustment of the Clough hysteresis model, involving the strength deterioration of reinforcement due to effective hysteretic energy dissipation under cyclic loading, together with loss of load capacity caused by interface bond-slip, buckling, and fracture of rebar. Finite element analysis was performed based on AbaqusExplicit module for typical reinforced concrete column and shear wall, respectively, to demonstrate the application of tj_fiber. The numerical results show that using finite element analysis with tj_fiber accurately simulates the local and global behavior of reinforced concrete compression-flexure members subjected to cyclic lateral load. |
