Abstract
이 연구에서는 SC 전단벽의 전단 연결재인 스터드의 배치와 형상이 SC 전단벽의 거동에 미치는 영향을 살펴보기 위해 전단벽체가 전단력과 축하중을 받을 때의 거동을 해석적으로 검토하였다. 이를 위해 서로 다른 형상과 배열의 스터드가 배열된 SC 전단벽을 대상으로 유한요소해석을 수행하였다. 스터드의 간격이 과하게 떨어져 있을 경우 합성거동이 완벽하게 작용하지 못하며 강판이 설계곡선의 2차 항복 전단력 보다 적은 하중에서 항복함을 확인하였다. 스터드의 형상은 일반형 스터드뿐만 아니라 개선된 경사형 스터드도 전단거동에 큰 차이를 나타내지 않았고, 스터드의 간격이 합성거동에 영향을 미침을 확인하였다. 또한 이 연구를 통하여 경사형 스터드가 일반형 스터드에 비해 좌굴을 제어하는데 효과가 있음을 확인하였다. In this study, the behavior of Steel Plate Concrete (SC) walls subjected to shear and axial forces to investigate the effects of shape and arrangement spacing of studs on the design of SC walls was analytically reviewed. For this purpose, 9 cases of finite element analyses considering the different shape and spacing of studs in SC wall were performed. The results showed that the steel plate was yielded at the lower load than the second yielding shear force of the design skeleton curve when the spacing of stud is excessively far from each other. It is also found that the shape of the stud did not affect the shear behavior of SC wall but, the spacing influenced to its composite action. In this study, it was also proven that the inclined shaped stud resists more effectively to the bucking load than the general shaped stud in SC wall.
