Abstract

Concrete filled tubular columns are widely used because the mutual reaction between the concrete and the tube improves strength and ductility of the columns. In an attempt to secure efficient use of members, built-up square columns featuring large width-thickness ratio and the use of thin steel plates are suggested in this study. In order to evaluate the structural characteristics and seismic performance of the column-to-beam connections of the new shape columns, cyclic load test of T-shaped column-to-beam connections was conducted with variables of diaphragms and concrete-filling. Moment-rotational angle relationship, dissipated energy and failure behavior were compared to evaluate stress transfer mechanism of the new shape built-up square column-to-beam connections associated with the variables.

콘크리트 충전형 기둥은 두 재료의 상호작용으로 인해 강도와 연성이 증대되어 기둥부재로 많이 사용되고 있다. 부재를 효율적으로 사용하고자 하는 노력에서 얇은 강판을 사용한 폭두께비가 큰 용접조립각형 기둥형상을 제안하였다. 세장비가 큰 용접조립 각형 기둥-보 접합부에 관한 연구로써 구조적 특성을 명료하게 평가하고 접합부의 내진성능을 고찰하고자 한다. 따라서 본 논문에서는 T자형 기둥-보 접합부의 반복가력 실험을 수행하였으며, 주 변수는 다이아프램 설치 유무와 콘크리트 충전유무이다. 모멘트-회전각 관계, 소산에너지, 파괴거동등을 비교하여 변수에 따른 용접조립각형기둥-보 접합부의 응력전달 메커니즘을 평가하고자 한다.
