This paper reports experimental results of reinforced concrete L-shaped section shear walls with varying horizontal loading direction. The deforming directions of the walls subject to horizontal forces are five directions dividing the angle of the weak axis from the strong axis into four equal angles. The results are as follows : (1) Initial stiffness and cracking loads remarkably change with varying deforming direction. (2) The flexural strength can be calculated by the eq. (3), considering the projected position of steel after projecting L-shaped section on a line of deforming .direction. (3) Each shear strength of two walls of L-shaped section shear walls decreases as the out-of-plane deformation becomes larger.
