Abstract

This paper reports a new beam-to-column connection that is suitable for use in the weak axis of a column. The proposed system mainly uses bolts, and it minimizes the use of welding, which is generally difficult to perform onsite. In this system, a H-shape steel beam is joined to a H-shape steel column by bolted splices at the top flange and without a scallop at the web. The structural performance of the proposed connection was verified through full-scale tests of nine specimens, taking into account the effects of the geometry and arrangement of the plate.

현재 가장 많이 사용되는 기존 약축접합부는 브라켓 타입으로 기둥과 보를 접합하는 과정에서 수평 스티프너가 필요하며, 기둥과 브라켓의 용접접합으로 인해 용접량이 비교적 많아 접합부에서 취성파괴가 우려된다. 본 논문은 용접플레이트를 사용함으로써 기존 약축접합부가 가지는 문제점에 대한 해결책을 제시할 수 있는 신형상 약축접합부를 제작해 기존 약축접합부 및 표준 약축접합부와 비교하여 구조성능을 평가하였다. 신형상 약축접합부는 H형강 기둥웨브에서 보 단부사이의 거리를 50mm, 100mm, 150mm, 200mm로 하였다. 실험결과 신형상 약축접합부는 H형강 기둥웨브와 보 단부사이의 거리가 150mm일 때 기준 실험값과 가장 비슷한 것으로 나타났으며, 기존 약축접합부와 표준 약축접합부와 비교해 우수한 구조성능을 가지는 것으로 나타났다.
