To analyze the strength degradation of RC beams subjected to high cyclic deformations, the test results of cyclic loading for RC beam with high strength material, which the variable parameters are number of cycle, with or without of slab and shear strength safety margin, is used. The ductility limit point and the ratio of strength degradation (including stiffness degradation) are defined as an index of strength degradation and the relationship between strength degradation and above parameters is investigated. In addition, the deformation is divided each component (flexure, shear, slip) and the relationship between the ratio of shear deformation component subjected to high cyclic deformations and strength degradation is revealed. As a result of those investigations, the analyzed equations related to strength degradation under high cyclic deformations are shown.
