プレキャスト連層財力壁の水平接合部のすべり強度に関する実験

抄録

A multi-story shear wall has often discrete joints without cotter reinforcements at the vertical joints between the wall panels and the surrounding cast-in-place columns. The sliding displacement in joints which display a resistance mechanism different from that of cast-in-place shear wall is expected to occur. In order to investigate the effect of resistant of joints on earthquake resistant performance, a shear failure type experiment was performed on seven multi-story precast concrete walls having a variety of cotter and joint reinforcement ratio at joints. Based on the results of this experiment, the resistance mechanism of a precast concrete multi-story shear wall and a design formula of the slip strength of horizontal joints are proposed.
