Abstract

In the existing study of steel beams with openings, openings are located at a location where the distance to the support point is equal to or greater than the section height. Considering the facilities using the openings in the steel beam, the distance from the opening to the support point may be closer than the height of the beam section. Therefore, research on this is needed. This study is an experimental study to understand the structural performance of beams with openings close to the ends subjected to Cyclic Loading. In addition, in this study, we want to understand the structural performance through experiments on beams with openings reinforced with vertical or horizontal steel plates.

유공 강재보에 대한 기존연구는 개구부의 위치가 강재보의 지지점까지의 이격이 보 단면 높이 이상인 경우가 다수이다. 유공 강재보의 개구부를 사용하는 덕트 및 배관 등의 설비시설의 배치를 고려할 때, 개구부는 강재보 지지점까지 이격이 보 단면 높이보다 가까운 경우가 있으므로 이에 대한 연구의 필요성이 대두된다. 본 연구는 지지점에 근접하게 개구부가 설치된 유공 강재보에 반복하중 가력에 따른 구조성능을 파악하는 실험연구이다. 또한 유공 강재보에 수직·수평 강판을 이용한 개구부 보강에 대하여 실험을 통하여 보강성능을 파악하고자 한다.
