Abstract

This study investigated the tension-field action induced strip angle changes and deformed mode shapes of SPSW for high-rise structures subjected to lateral forces. Based on the numerical analysis 3, 9, 14 and 20 story structures, shear and flexural modes were identified by comparing the numerical analysis results to the predicted strength by theory. Shear deformation mode exhibited a constant angle in tension-field; whereas, flexural mode of the numerical results, differed from the tension-field action theory.

횡하중을 받는 고층건물에서의 인장역이 형성될 때 강판전단벽의 앵글 변화한다. 본 연구에서는 강판전단벽을 갖는 3층, 9층, 14층 및 20층의 4개 구조물에 대한 유한요소해석 연구를 하였다. 유한요소해석 결과와 각 모델들의 이론식으로 계산된 결과를 비교하여 전단변형 모드와 휨변형 모드로 분류하였다. 전단변형 모드의 모델에서는 주응력 벡터가 일정한 경사각을 이루며 인장역을 발생시킨 반면 휨변형 모델에서는 인장역의 변화는 기존의 이론식과 차이를 보였다.
