Abstract

The purpose of this study was to investigate the seismic performance of reinforced concrete bridge columns with interlocking circular hoops. Three interlocking columns were tested under a constant axial load and a quasistatic, cyclically reversed horizontal load. A computer program, RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology) was used for the analysis of reinforced concrete structures. The used numerical method gives a realistic prediction of performance throughout the loading cycles for several test specimens investigated. Based on the experimental and analytical results, design recommendations are presented to improve the existing practice in the design and construction of reinforced concrete bridge columns with interlocking circular hoops.

이 연구의 목적은 결합원형띠철근을 갖는 철근콘크리트 교각의 내진성능을 파악하는데 있다. 3개의 인터락킹 교각 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. 실험적, 해석적 결과로부터 결합원형띠철근을 갖는 철근콘크리트 교각의 설계와 시공 실무를 향상하기 위한 상세를 제시하였다.
