내진보강 섬유의 재료별 특성에 따른 기둥의 내진성능 효과 분석

초록

Composite plate composed of fiber and perforated aluminum plate is lightweight and mass produced in order to consistent quality and rapid construction. It is appropriate for seismic retrofit system of the existing railway concrete structures. In this study, concrete column experiments reinforced by composite plate made of 4 types of FRP(carbon fiber, glass fiber, high performance glass fibers and aramid) with perforated aluminum plate were tested under lateral cyclic loading. Comparing load-displacement relation, failure modes, initial stiffness and ductility, plate composed of high performance glass fiber was found better performance than the others.
