Research Abstract	This study describes flexural shear cyclic loading test results of reinforced concrete member in various viscous liquid, with focusing on fatigue characteristic due to liquid permeation into cracks of the member. As a result, it was obtained that the viscous difference of liquid influences crack progress and fatigue strength. Furthermore, it was obtained that the fatigue life is affected by the difference of rate of cyclic loading.
