Abstract

This paper analyzed the reinforcement effect of concrete beam-to-column joints bonded with steel plate in reinforced concrete structures using finite element program. The limit load, ductility, and cracks of unreinforced model and reinforced model by steel plates were evaluated based on the analytical variations of reinforced steel plate area and thickness. As a result of analytical study, the maximum load of reinforced model by steel plate has 63% to 97.5% against unreinforced model. Also, to increase steel plate thickness has better performance than when steel plate area increases.

본 연구에서는 유한요소해석 프로그램인 ABAQUS를 통하여 철근콘크리트 구조물 보-기둥 접합부의 강판보강효과를 평가하였다. 해석변수로는 강판의 보강면적과 보강강판의 두께를 두어 해석연구를 수행하였다. 해석결과 강판보강 시 최대 하중은 약 63~97.5% 증가하였고, 내진성능도 크게 향상되었다. 또한 보강강판의 면적을 증가 시키는 것보다 두께를 증가 시켰을 때 내력이 크게 증진되었다.
