본 연구에서는 피난안전구역이 한 개 층 설치된 준초고층 골조-전단벽 건물의 풍하중에 대한 거동을 파악하기 위하여 KDS2022의 스펙트럼을 이용하여 풍방향 및 풍직각방향 풍하중을 생성하고, 생성한 풍하중을 적용하여 임의의 층에 벨트 트러스가 설치된 골조- 전단벽 건물의 동적 해석을 실시하여 풍하중에 대한 동적 거동을 분석한다. 코어의 위치에 따른 편심과 벨트 트러스가 동적 응답에 미 치는 영향을 평가하고자 한다.

Most commercial buildings among existing RC buildings in Korea have a multi-story wall-frame structure where RC shear wall is commonly used as its core at stairways or elevators. The members of the existing middle and low-rise wall-frame buildings are likely arranged in ordinary details considering building occupancy, and the importance and difficulty of member design. This is because there are few limitations, considerations, and financial burdens on the code for designing members with ordinary details. Compared with the intermediate or unique details, the ductility and overstrength are insufficient. Furthermore, the behavior of the member can be shear-dominated. Since shear failure in vertical members can cause a collapse of the entire structure, nonlinear characteristics such as shear strength and stiffness deterioration should be adequately reflected in the analysis model. With this background, an 8-story RC wall-frame building was designed as a building frame system with ordinary shear walls, and the effect of reflecting the shear failure mode of columns and walls on the collapse mechanism was investigated. As a result, the shear failure mode effect on the collapse mechanism was evident in walls, not columns. Consequently, it is recommended that the shear behavior characteristics of walls are explicitly considered in the analysis of wall-frame buildings with ordinary details.
