The non-linear behavior of reinforced concrete members have been pursued experimentally by many researchers and Clough-model and Takeda-model are perceived to be working models to describe the non-linear behavior. However, still remains a room where the possibility to enhance the damping capacity of reinforced concrete members are pursued by applying exquisite model such as Degrading Tri-linear model. In this paper, results of experiment are reported which cover the difference in yielding type (shear yielding or flexural yielding) material strength. Emphasis is placed in the range of deformation prior to the yielding of reinforcing bars. The test results are compared with proposed models and it is concluded that Takeda model keeps firm precedence and Degrading Tri-linear model should be excluded on the reason of its over estimate of damping capacity in the smaller deformation range.
