Abstract

Cyclic loading tests for beam-to-column weak-axis connections were performed to investigate the seismic performance. In this study, the connections were developed to improve the constructability on the basis of investigation for existing small-size steel structures. The primary test parameter is the number of high-tension bolts which are used to connect steel beam and column using exterior and interior flange plates. Test results showed that the number of bolts had a significant effect on the cyclic behavior of beam-column weak-axis connections. From the analysis of test results, it is concluded that more than four bolts in the connections can satisfy the requirements of semi-rigid connection presented in current design codes. All of specimens showed the bearing failure around bolt holes and fracture at the beam flange. However, when the web height and the flange width is relatively small, the number of the bolts used in the connections might be limited. Thus, the additional research in this area is needed.

본 연구에서는 국내 소규모 철골조 건축물에서 실제 시공된 보-기둥 약축 접합부에 대한 현황조사를 바탕으로 시공성을 향상시킨 약축접합부 상세를 제안하였으며, 제안된 약축접합부에 대한 반복가력 실험을 통해 접합부 내진성능을 평가하였다. 실험변수는 보-기둥 접합부에 사용된 볼트의 개수이다. 실험결과, 본 연구에서 제안하고 있는 보-기둥 약축 접합부의 거동은 수평 스티프너에 연결되는 고력볼트의 개수의 의해 결정되는 것으로 나타났다. 접합부에 4개 이상의 볼트접합이 사용될 경우 현행 기준에서 요구하는 부분 강접합 요구조건을 만족시키는 것으로 나타났다. 모든 실험체는 플랜지 연결플레이트의 연단쪽 보 플랜지 볼트 구멍 주위에서 국부적인 지압파괴와 파단 등이 발생하였다. 하지만, 웨브 높이와 플랜지 폭이 작은 기둥을 사용할 경우, 접합부에 사용되는 고력볼트의 개수가 제한적으로 사용되어야 할 것으로 판단되므로 향후 이 부분에 대한 추가적인 연구가 필요하다.
