EXPERIMENTAL STUDIES ON THE SHERE WALL-FLOOR SLAB JOINT OF PRECAST CONCRETE STRUCTURE USING JOINT BARS UNDER INCLINED ARRANGEMENT : Studies on the horizontal joint of the RC precast shear wall

Abstract

Recently there are many cases in Japan to build by RC precast structures. It is important to make clear the shear behavior of RC precast structures, especially that of member-to-member joints. The easiness of connecting member with member is also important. The authors designed a new joint method connecting shear wall with floor slab, which was used by mesh bars under inclined arrangement. On this study the authors performed experiments under shear force to investigate the seismic behavior of this new joint method and to try to establish estimating method of the shear strength of joints on precast structure. We took the result that the new joint method hadgood capacity for shear force and good hysteresis, and that we can calculate the shear strength of the new method by the cumulative strength method to a certain extent.
