초록

본 논문은 모르타르에 근입되어 인발하중을 받는 정착판 GFRP 근의 인발거동을 기술하고 있다. 정착판 GFRP 근의 모르타르 시험체를 5개 제작하여 인발시험을 수행하였다. 시험 결과를 검증하기 위해 ANSYS 상용프로그램을 이용한 유한요소해석을 수행하였으며 시험결과와 비교되었다. 시험결과 모르타르에 매입된 정착판 GFRP 근의 파열 파괴강도식은 45도 콘(Cone)파괴 이론 보다는 CCD(Concrete Capacity Design)파괴이론을 적용하는 것이 타당한 것으로 나타났다.

This paper presents the pull-out behaviors of headed glass fiber reinforced polymer (GFRP) rebar embedded in mortar under tension loading. Five specimens with headed GFRP rebars that were anchored in the center of mortar bases were constructed and the pull-out test was conducted. To verify the test results, the finite element analysis was conducted and the results were compared with the FE analysis using ANSYS software package. Based on the test results it was indicated that the CCD(concrete capacity design) failure theory should be adopted and not to use the 45o cone failure theory as the breakout capacity in the headed GFRP rebar embedded in mortar.
