Abstract

강재의 강지적인 사용으로 인한 부식 등과 같은 문제점을 보완할 수 있는 대체 재료로서, 섬유강화 복합재료의 활용이 증대되고 있다. 하지만 일반적으로 선형의 섬유강화 복합재료를 아치형인 터널구조물의 부재로서 활용하는 데는 많은 문제점이 대두된다.본 연구에서는 FRP 복합부재의 거동특성 파악을 위해 FRP와 콘크리트 합성부재에 대한 하중재하 실험을 수행하였다. 또한 역학적 거동분석을 위하여 동일 조건에 대한 수치해석을 수행하였다. 하중재하 실험 및 수치해석결과, FRP와 콘크리트 계면특성을 고려하는 것이 보다 합리적인 해석방법인 것으로 나타났다.

Utilization of fiber reinforced polymer(FRP) material has been increased to solve construction material problems such as corrosion, etc. However, there are still many problems in using a linear-shaped FRP material for a tunnel structure with curved section. In this study, the loading tests were performed on the curved FRP-concrete composite material to evaluate its behavior as tunnel support. These tests were based on the result from preliminary numerical analysis on FRP- concrete composite material. Also, additional numerical analysis considering interface characteristics between FRP and cement-concrete was conducted to compare the result of loading test on FRP-concrete composite material. From the results of the loading test and numerical analysis, the analysis method suggested from this study is reasonable to evaluate the mechanical behavior of FRP-concrete composite material.
