Abstract

The purpose of this study was to investigate the seismic behavior of hollow circular reinforced concrete bridge columns with confinement steel, and to develop improved seismic design criteria. Three hollow circular columns were tested under a constant axial load and a quasi-static, cyclically reversed horizontal load. The accuracy and objectivity of the assessment process can be enhanced by using a sophisticated nonlinear finite element analysis program. The numerical method used gives a realistic prediction of the seismic performance throughout the loading cycles for the several test specimens investigated. Based on the experimental and analytical results, design recommendations are presented to improve current practice in the design and construction of hollow circular reinforced concrete bridge columns.

이 연구의 목적은 중공원형 철근콘크리트 교각의 횡방향철근에 따른 지진거동을 파악하고 합리적이면서 경제적인 내진 설계기준의 개발을 위한 자료를 제공하는데 있다. 3개의 중공원형 교각 실험체에 일정 축하중 하에서 횡방향 반복하중을 가하는 준정적 실험을 수행하였다. 정확하고 올바른 성능평가를 위하여 신뢰성 있는 비선형 유한요소해석 프로그램을 사용하였다. 이용된 해석기법은 조사된 실험체에 대하여 하중단계에 따라 내진성능을 비교적 정확하게 예측하였다. 실험적, 해석적 결과로부터 중공원형 철근콘크리트 교각의 설계와 시공 실무를 향상하기 위한 내진상세를 제시하였다.
