Abstract

In this paper, the design load acting on a main girder(spine girder) of fish-bone girder pier is proposed. In order to check the structural safety, numerical analyses using finite element program ABAQUS are performed. It is found that the main girder is affected by a torsional behavior as well as a bending behavior and the major influence loading is the torsional loading. Also, from the stress evaluation of the chosen cross section of the main girder, chosen fish-bone girder pier is structurally safe.

본 논문에서는 경골잔교의 Main girder에 작용하는 설계하중을 제안하였다. 구조 안전성 검토를 위하여 범용 유한요소 프로그램인 ABAQUS를 이용하여 수치해석을 실시하였다. 경골잔교의 Main girder는 휨뿐 아니라 비틀림 거동에 영향을 받고 있음을 알 수 있으며 주요 영향 하중은 비틀림이다. 또한 선정된 Main girder 단면에 대한 응력 검토를 통해 선정된 경골잔교는 구조적으로 안전하다.
