DEVELOP THE HYSTERESIS MODEL OF CONCRETE BASED ON FIBER ELE-MENT IN ABAQUS
Due to the complicated material behavior during the earthquake, the precision of simulation mainly depends on the hysteresis model of concrete and reinforcement. ABAQUS has strong nonlinear analysis ability, but its damaged-plastic model for concrete does not support spatial beam element. Therefore, the uniaxial hysteresis model suitable for fiber mod-el of concrete was developed by using the interface UMAT in this paper. The fiber beam mod-el is suitable for global elastic-plastic analysis of frame which is subjected to the combined action of cyclic lateral and gravity loads. The model is verified by experiments and the results show that the fiber model developed by authors possesses better accuracy and time-saving compared with traditional finite element model using solid element. It can be used with high calculation efficiency to analyze frames subjected to cyclic loading due to earthquake.
