Abstract
연안역 조립식 경골잔교는 단일거더 시스템이므로 비틀림에 큰 영향을 받는 구조물이다. 본 연구에서는 이 잔교를 합리적으로 해석하고 설계하기 위한 해석모델을 개발하고자 하였다. ��강성을 포함한 7자유도 보요소를 사용한 해석모델의 구속조건을 조절하여 해석모델을 선정하였으며, 선정된 해석모델은 실물크기의 실험체를 이용한 정적하중재하 실험을 통하여 검증하였다. 실험결과와의 비교분석을 통하여 개발한 해석모델을 입증하였으며, 이 해석 모델을 이용하여 연결부의 단면력을 산정함으로써 합리적인 연결부 설계를 가능하게 하였다. A fish-bone girder pier affects torsion severely because of the one girder system. This study was performed to develop an analytical model to analyze and design a fish-bone girder pier properly. This model consisted of a beam element with 7-degrees of freedom considering the warping rigidity. Several beam-column connection conditions were considered. The static load test was performed using a real size specimen. The validity of this model was tested by a comparison of the analytical results with the experimental results. This analytical model is useful for designing the bolt connection of a Spine girder.
