초록

복합 병렬 전단벽(Coupled shear walls)은 커플링 보와 철근콘크리트 벽체로 구성되어 바람이나 지진 등의 횡하중으로부터 유발된 전도모멘트의 상당 부분을 철골 연결보의 커플링 작용에 의하여 골조 작용(Frame action)을 의하여 횡력에 효율적으로 저항하게 된다. 본 연구에서는 접합부 상세에 따른 복합병렬 전단벽의 접합부 강도에 대한 규준식을 정립하기 위한 선행연구로서 병렬 전단벽 접합부에서 커플링 보의 매립길이 및 벽체 두께를 주변수로 실험적 연구를 수행하여 접합부 상세에 따른 복합 병렬 전단벽 시스템의 거동특성을 규명하고자 하였다. 본 실험결과, 실험체의 거동 및 내력은 매립길이 및 접합부 상세에 많은 영향을 받는 것으로 나타났으며 향후 설계시 이에 대한 영향을 반영해야 할 것으로 판단된다.

In high multistory buildings, hybrid coupled shear walls can provide an efficient structural system to resist horizontal force due to wind and seismic loads. Hybrid coupled shear walls are usually built over the whole height of the building and are laid out either as a series of walls coupled by steel beams with openings to accommodate doors, elevator walls, windows and corridors. In this paper, the behavior characteristics of hybrid coupled shear wall system considering connection details is examined through results of an experimental research program where 5 two-thirds scale specimens were tested under cyclic loading. Such connections details are typically employed in hybrid coupling wall system consisting of steel coupling beams and reinforced concrete shear wall. The test variables of this study are embedment length of steel coupling beam and wall thickness of concrete shear wall. The results and discussion presented in this paper provide fundamental data for seismic behavior of hybrid coupled shear wall systems.
