Abstract
A Practical 1D cyclic model for concrete is established. The model is a combination between the skeleton curves in Chinese Concrete Code (GB50010-2010) and the modified hysteretic rule in Yassin model. The cyclic model has the tensile and compress damage variables which are able to depict the damage of concrete. The present model is developed as a user material subroutine VUMAT in ABAQUS. Then, the damage evolution analysis of a RC tall building structure was performed by the proposed damage model and the built-in damage model for concrete in ABAQUS. The results show that the cyclic model is suitable for the damage evolution and pattern analysis of RC tall building structures under earthquake loading.
