Abstract

This study was conducted to identify the structural performance of the opening in a location close to the support point in the perforated beam system of steel beams. In addition, structural performance was determined through experiments on reinforced openings using vertical and horizontal steel plates. In the steel simple beam, it was found that the opening was in a position closer to the support point, half the height of the steel beam (D/2), which was more appropriate than the height of the steel beam (D). In addition, the reinforcement effect of horizontal steel plate was greater than that of vertical steel plate reinforcement. Structural performance was improved when there was no gap between openings and steel plates.

본 연구는 강재 단순보의 유공보 시스템에서 개구부를 지지점 에 근접한 위치에 설치하는 경우에 대하여 구조성능을 파악하고자 실험을 실시하였다. 또한 수직·수평 강판을 이용한 개구부 보강에 대하여도 실험을 통하여 구조성능을 파악하였다. 강재 단순보에서 개구부가 지지점에 근접한 위치인 강재보 높이의 절반(D/2)인 경우에 강재보 높이(D)인 경우보다 적절한 개구부 위치인 것을 알 수 있었다. 또한 보강방법으로는 수직강판 보강보다는 수평강판 보강이 보강효과가 크며, 개구부와 강판의 간격이 없는 것이 구조성능이 더 큰 결과를 얻을 수 있었다.
