초록
모듈형 구조시스템은 학교 및 아파트 건물과 같은 저층 및 중층 구조물에 점점 더 많이 사용되고 있다. 최근에는 고층 건물에 모듈러구조시스템을 적용하는 방법에 대한 연구가 수행되고 있다. 고층 모듈러 구조시스템에 대해 충분한 저항력과 경제적인 구조를 제공하기 위해복합모듈 구조시스템이 제안되었다. 본 연구에서는 일련의 실험을 통해 단위 복합모듈 구조에 적용하기 위한 목적으로 비대칭 복합 기둥의 강도를 평가하고자 하였다. 실험적 연구는 기둥의 세장비, 편심율 및 관통바 유무에 따라 기둥의 강도에 미치는 영향에 중점을 두었다. 단위 모듈구조에 대한 비대칭 기둥단면의 설계식을 제안하였다. 결과로부터, 설계식은 단위 복합모듈 구조에서 비대칭 기둥단면의 적절한 강도 예측을제공한다는 것을 알 수 있다.
Abstract
Modular structural systems have been used increasingly for low- and mid-rise structures such as school and apartment buildings. Studieshave recently been conducted on the application of the modular structural system to high-rise buildings. To provide sufficient resistances and economicalconstruction for the high-rise modular structural system, a composite unit modular structure was proposed. In this study, the strength of thenon-symmetric composite column for the proposed composite unit modular structure was investigated through a series of tests. The experimentalstudy focused on the effect of the slenderness of the column, eccentricity, and through bars on the strength of such a column. Design equations forthe non-symmetric column for a modular unit structure were also proposed. From the results, it was found that the proposed design equations providereasonable strength prediction of the non-symmetric composite column for the modular unit structure.
