EXPERIMENTAL STUDY ON STRUCTURAL PERFORMANCE OF RC SHEAR WALL WITH L SHAPED SECTION
Recently, many high-rise buildings with the center core structure system having high strength reinforced concrete shear walls have been constructed in Japan. Severe earthquake design forces cause huge bending moment and axial load at the bottom of the walls. Especially in the shear walls with L shape section, the improvement of compression ductility at the corner of the wall is needed. This paper aims to observe the structural performance of the L shape walls and to investigate the correspondence between experimental and analytical results by section analysis using fiber model. In this study, four specimens of 1/6-scale were produced, and horizontal shear loads were applied under varied axial loads. Parameters are concrete strength and bar arrangement. The corner part was confined by the lateral reinforcing bars. The analytical and the experimental results showed a good correspondence.
