초록

본 연구에서는 라멘구조의 단면효율성을 개선하는 방법을 마련하기 위하여 H형강을 활용한 프리스트레싱 도입 합성형 라멘구조를 제안하였다. 이를 위하여 H형강과 전단연결판의 단면효율성 분석하여 적절한 라멘구조 단면을 개발하였으며, 프리스트레싱 도입 H형강 합성형 라멘구조의 시공절차를 마련하였다. 제안된 시공절차를 활용하여 구조실험체를 제작하고, 하중재하실험을 진행하였다. 하중재하실험 결과로부터 하중이 증가함에 따라 발생하는 프리스트레싱 도입 H형강 합성형 라멘구조의 하중저항거동을 평가하였다. 또한, 구조해석을 통하여 프리스트레싱의 효과를 검토하였으며, 하중저항거동을 하중재하실험 결과와 비교 및 평가하였다.

Abstract

In this study, a prestressed composite rahmen structure using H-shaped steel was proposed to improve the cross-sectional efficiency of rahmen structures. The cross-sectional efficiency of the H-shaped steel and shear connectors was analyzed to achieve this goal, and an appropriate cross-section for the rahmen structure was developed. The construction process for the prestressed composite rahmen structure using H-shaped steel was also developed. The proposed construction process was used to fabricate a structural specimen, and a loading test was conducted. Based on the loading test results, the load-resistant behavior of the prestressed composite rahmen structure using H-shaped steel was evaluated as the load increased. Additionally, the effect of prestressing was examined through structural analysis, and the load-resistant behavior was compared and evaluated against the loading test results.
