The uniaxial stress-strain curves of concrete suggested in Chinese Concrete Standard (GB50010-2010) are combined with the modified Yassin hysteretic rule. The integrated cyclic constitutive model for concrete is aimed at the nonlinear analysis of the reinforced concrete (RC) structures under strong earthquake. The model is implemented into general-purpose FEA software ABAQUS through the user material subroutine VUMAT. Then, some typical performances of the proposed model are verified. Furthermore, a seismic damage analysis of a multi-story RC frame structure is conducted using the cyclic model. The results show that the constitutive model is applicable to the nonlinear seismic analysis of RC structures.
