This paper describes the evaluation method of hysteresis model for reinforced concrete beams and columns subjected to shear failure after flexural yielding. Deterioration due to cyclic loading after flexural yielding is modeled using the ductility factor at the start of deterioration μwy and factor representing the degree of deterioration A : μwy and A are determined based on the results of previous studies that focused on the shear deformation behavior and effectiveness of lateral reinforcement. As a result of comparison between the proposed model and test results, it is found that the model can accurately simulate the behavior of the member. Seismic response analysis is also carried out by single degree of freedom system using proposed model to identify the characteristics of response in the case of shear failure after flexural yielding.
