Abstract

The purpose of this study was to investigate the performance of solid reinforced concrete columns with triangular reinforcement details. The proposed reinforcement details has economic feasibility and rationality and makes construction periods shorter. A model of solid reinforced concrete columns with triangular reinforcement details was tested under a constant axial load and a quasi-static, cyclically reversed horizontal load. A computer program, RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology), for the analysis of reinforced concrete structures was used. The used numerical method gives a realistic prediction of performance throughout the loading cycles for several test specimens investigated. As a result, proposed triangular reinforcement details for material quantity reduction was superior to existing reinforcement details in terms of required performance.

이 연구의 목적은 삼각망 철근상세를 갖는 중실 철근콘크리트 기둥의 성능을 파악하는데 있다. 제안된 철근상세는 경제성과 합리성을 갖으며 공사기간의 단축을 가져올 수 있다. 삼각망 철근상세를 갖는 중실 철근콘크리트 기둥 실험체에 일정 축하중 하에서 횡방향 반복하중을 가하는 준정적 실험을 수행하였다. 사용된 프로그램은 철근콘크리트 구조물의 해석을 위한 RCAHEST이다. 사용된 해석기법은 조사된 실험체에 대하여 하중단계에 따라 성능을 비교적 정확하게 예측하였다. 그 결과 제안된 삼각망 철근상세는 기존 철근상세와 동등 이상의 소요성능을 보임을 확인하였다.
