Strain Hardening Cementituous Composite (SHCC) shows Pseudo Strain Hardening behavior (PSH behavior) under tensile stress. The purpose of this study is to verify the influencing factors on shear strength and deformation capacity of dampers using SHCC. In this study, the structural tests using SHCC dampers are conducted to obtain the basic data on shear behavior. The test variables are shear reinforcement ratio, depth to width ratio of cross sectional area, width span ratio, presence of flexural yielding, and the in- fluence of hysteresis cyclic loading. On that basis, the shear resistance properties of dampers using SHCC are examined based on the results of experiments. The test results offer the following conclusions. When the shear failure occurs without flexural yielding, the value of shear strength is the same as that of RC member using SHCC tensile stress instead of shear reinforcement. When it occurs with flexural yielding, the value of deformation capacity is larger than RC members with the same condition. In case of cyclic loading, the larger difference between two values of each can be observed.
