  • 발행 : 2002.08.01

초록

본 연구는 철근콘크리트 모멘트골조 기둥의 구조적인 성능을 평가하는 것이다. 이를 위하여 기존에 진행된 연구들의 실험결과를 모아 비교하였다. 본 연구에서 고려하는 실험변수는 소성힌지 부분에서 철근이음 유무, 종 방향 철근 비, 횡 방향 철근 비, 축력비이다. 또한, 본 연구에서는 시험체의 강도, 변위, 연성능력과 함께 소성힌지 길이를 비교하였다.

This study is to evaluate the structural performance of columns in concrete moment frame. For this purpose the results of previous experimental studies were collected and compared. The experimental variables considered in this study are existance of lap splice within the possible plastic hinge region during an earthquake, ratio of longitudinal reinforcement axial load and the transverse reinforcement ratio. The strength, deformation, ductility capacity and the length of plastic hinge are compared in this study.
