Abstract

The purpose of this study is to critically evaluate the structural performance of an innovative new shear resistance connecting structure of precast member. Joints such as shear resistance connecting structure require special attention when designing and constructing precast segmental structures. An experimental and analytical study was conducted to quantify performance measures and examine one aspect of detailing for developed shear resistance connecting structure. A computer program, named RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology), for the analysis of reinforced concrete structures was used. A joint element is used to predict the inelastic behavior of the joints between segmental members. Future work by the authors will do a model test of precast segmental prestressed concrete bridge columns with this shear resistance connecting structure, and examined both the structural behavior and seismic performance.

이 연구의 목적은 프리캐스트 부재의 새롭게 고안한 전단저항 연결체의 구조성능을 평가하는데 있다. 프리캐스트 세그먼트 구조물의 설계와 시공시에 전단저항 연결체와 같은 접합부는 특별한 주의가 요구된다. 개발한 전단저항 연결체의 상세와 성능을 평가하기 위하여 실험 및 해석적 연구를 수행하였다. 사용된 프로그램은 철근콘크리트 구조물의 해석을 위한 RCAHEST이다. 이 연구에서 사용된 접합요소는 세그먼트 접합부의 비탄성거동을 정확하게 예측할 수 있다. 추후 전단저항 연결체를 갖는 프리캐스트 세그먼트 PSC 교각의 실험을 수행하여 구조거동과 내진성능을 파악할 것이다.
