초록
이 연구의 목적은 P-delta 영향을 고려한 프리캐스트 세그먼트 PSC교각의 성능을 파악하는데 있다. 개발된 프리캐스트 세그먼트 PSC교각 실험체에 일정 축하중 하에서 횡방향 반복하중을 가하는 준정적 실험을 수행하였다. 사용된 프로그램은 철근콘크리트 구조물의 해석을 위한 RCAHEST이다. 비교적 큰 압축하중과 함께 지진하중과 같이 큰 규모의 횡하중으로 인한 대변위 문제를 고려할 수 있도록 Total Lagrangian 정식화 기법을 사용하였다. 이 연구에서는 반복하중을 받는 프리캐스트 세그먼트 PSC교각의 실험적, 해석적 결과를 제시하였다.
Abstract
The purpose of this study was to investigate the performance of precast segmental PSC bridge columns with regard to P-delta effects. A model of precast segmental PSC bridge columns was tested under a constant axial load and a 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. In addition to the material nonlinear properties, an algorithm for the problem of large displacement that may result in additional deformation has been formulated using total Lagrangian formulation. This study documents the testing of precast segmental PSC bridge columns under cyclic loading, and presents conclusions based on the experimental and analytical findings.
