Abstract

In this study, we performed an investigation on the variations in the structural capacity of steel plate walls with various infill plate details. Five three-story plate walls with thin web plates were tested. Parameters for the test specimens were the connection details between the moment frame and infill plates, such as weld and bolt connections, the location and length of weld connection, and coupling wall. Regardless of the details of infilled steel plate, the steel plate wall specimens showed excellent initial stiffness, strength, and energy dissipation capacity. However, the wall with bolt-connected infill plates showed slightly low deformation capacity. This result showed that for workability and cost efficiency,various wall details can be used in practice without causing a significant decrease in the structural capacity of steel plate walls. A method for making projections on strength and energy dissipation capacity of steel plate wall specimens with various details was developed.

웨브강판의 상세에 따른 골조강판벽의 거동특성을 연구하기 위하여 실험 연구를 실시하였다. 실험체는 웨브강판에 스티프너를 사용하지 않은 3층 골조강판벽을 1/3 축소모델로 제작하였다. 주요 실험 변수는 골조와 웨브강판의 연결 상세로서, 용접접합과 볼트접합, 강판의 용접부위 및 길이, 연결강판벽이다. 골조강판벽 실험체들은 대체로 실험변수와 관계없이 우수한 강도, 변형능력 그리고 에너지소산능력을 나타냈다. 다만, 볼트접합을 사용한 강판벽은 강판의 전 모서리를 용접한 강판벽보다 다소 작은 변형능력을 나타냈다. 이러한 결과는 시공성과 경제성 향상을 위해 강판 구조성능의 큰 손실 없이 다양한 상세를 사용할 수 있음을 보여주었다. 본 연구의 실험결과와 해석결과를 토대로 다양한 상세를 갖는 강판벽 실험체의 강도 및 에너지소산능력을 예측할 수 있는 방법을 제시하였다.
