Abstract

This paper analyzed structural behaviors of the staggered truss system, typically used in low seismicity regions, resisting the lateral loads such as wind and seismic load. A comparative study of cost and efficiency was carried out by analysing and designing the 10- and 20-story buildings with various types of truss, including pratt, howe, warren, K-, and vierendeel, which may typically be used in staggered truss system. In design, column and truss members are selected in group, and the efficiency of the member design was judged by average demand capacity ratio of the all members in same group. And economic analysis of the system was investigated by the quantity of the structural members. As a result, staggered truss system with the pratt truss and warren truss showed the most economical and efficient performance for 10-story building, and 20-story building, respectively.

본 논문에서는 약진 지역에서 적용되는 스태거드트러스 골조시스템의 수평하중에 대한 구조특성을 분석하였다. 스태거드 트러스 시스템에 적용되는 프랫, 하우, 와렌, K형, 비렌딜의 대표적인 트러스 형태를 기준으로 10층과 20층의 예제 건물에 대한 해석과 설계를 수행하여 트러스 형태에 따른 시스템의 경제성과 효율성을 비교․분석하였다. 설계에서 기둥 및 트러스 부재는 같은 부재를 몇 개 층씩 그루핑하여 사용하였으며 부재의 효율성은 그루핑된 부재의 평균 내력비를 기준으로 판단하 였으며 시스템의 경제성은 전체 골조물량을 기준으로 판단하였다. 분석 결과 효율성과 경제성 측면에서 10층의 예제에서는 프랫트러스를 사용한 시스템이 우수한 것으로 나타났으며 20층의 예제에서는 와렌트러스를 사용한 방식이 우수한 것으로 나타났다.
