초록

본 연구는 철골조 유닛 모듈러를 이용하여 중고층으로 적층할 수 있는 접합구조시스템을 개발하고자 하는 것이다. 기존 모듈러 유닛 간의 접합방법은 고층화하는데 기술적인 제약을 갖고 있어 횡력저항 내력을 증대시킬 수 있는 유닛 간 접합부의 상세가 필요하다. 제안된 유닛 간의 접합부의 횡력 저항에 대해 휨성능을 실험적으로 평가하고자한다. 주요변수에 따라 총 7개의 실험체를 제작하여 실험을 수행하였다. 유닛 간 접합부에 대한 실험결과, 절곡형 기둥을 제외한 모든 접합부는 특수모멘트 골조에 해당하는 성능을 확보하고 있는 것으로 파악되었다.

Abstract

This paper is a aim to develop a connection structure system that can be adapted using steel-frame middle & high-rise of the modular units. Conventional connecting method between the modular unit which is a high-rise or technical constraints problems. Lateral load resistance and increase strength of the details of the connection between the units are needed. Lateral load resistance of the connection between the proposed unit for the bending performance evaluated experimentally. Main variables in accordance with a total of seven specimens were fabricated and experiments were carried out. Experimental results for the connection between the units, All connections except the bending-type columns corresponding to the special moment frames to ensure that the performance was investigated.
