더블패널을 이용한 내력벽식 구조시스템의 수평접합부 거동에 관한 연구 ( Behavior of Wall-to-Floor Joint in Bearing Wall System with Double Precast Concrete Panel )

The purpose of this study is to investigate the behavior of the bearing wall system with double precast concrete panels by experiments. This bearing wall system has wall-to-wall joints (vertical joints) resisting the shear force and wall-to-floor joints (horizontal joints) resisting the bending moment. Four full-scale vertical joint specimens are tested under the pure shear. The experimental results were compared with the computed values according to the ACI and AIJ codes. The results show that the ultimate shear strength of the vertical joint in double precast concrete panel system using joint reinforcements is higher than the computed design value. The structural behavior of the double precast concrete panel system is similar to that of the reinforced concrete bearing wall system.
