Abstract
Most shear walls with steel reinforced concrete surrounding frames are designed in accordance with "the Standard of Reinforced Concrete Structures (RC) of A.I.J.", because few studies have been performed on shear walls with surrounding frame of steel reinforced concrete (SRC). In this study, to clarify the elastic-plastic behaviors of shear walls with SRC frames, shear walls with various surrounding frames were tested under alternating horizontal loads. The test program was composed of two series in which one is 6cm wall-thickness and the other is 10cm wall-thickness. Several types of fracture were observed even if wall-thickness is same, and the shear walls with SRC surrounding frame were ductile and strong rather than those with RC surrounding frame. It was recognized that the ultimate strength by the equation, which we proposed, agrees fairly good with the experimental results.
