Abstract

A through diaphragm is often used to ensure their stiffness for moment-resisting connections using rectangular steel-tube column and H-shaped beam. The through-diaphragm connections, however, have some difficulties for their applicabilities to the field due to the complexity of the fabrication and construction processes. This study thus proposes a new modular system of steel structures assembled only using bolts without welding, by bringing a connection module composed of rectangular steel-tube column, H-shaped beam and oneway bolt onto the site. An experimental study to evaluate the seismic performance of the proposed connection details based on the new modular system is then conducted. The length and type of the inner reinforcement plate are considered as the primary design parameters, and the strength, stiffness, ductility and energy dissipation capability of the new connections are experimentally analyzed by comparison to those of conventional through diaphragm connections.

각형강관 기둥을 이용한 모멘트 접합부는 주로 관통형 다이어프램 형식으로 사용되고 있으나, 제작 및 시공과정이 복잡하여 적용하는데 어려움이 있다. 본 연구에서 제안하는 강구조물 시스템은 단위 유닛 모듈(각형강관 기둥, H형강 보, 원웨이 볼트)을 현장으로 반입하여 볼트조립만으로 완성되는 것이다. 따라서 이 연구에서는 내부보강판의 길이, 내부보강판의 형상을 변수로 설정하여 제안된 기둥-보 접합부의 내력 및 강성, 연성능력, 에너지 소산능력을 비교 분석하여 제시된 강구조물 시스템을 평가하였다.
