Analysis of Curved Bridges by Finite Element Method
Abstract
도로교 선형에 Curved box-girder를 사용하는 것은 구조적으로 큰 효과를 얻을 수 있다.

교량의 상하슬랩은 Sector plate 요소로, Web 부분은 원통 Shell 요소롤 분할했다. 절점자유도는 12개씩이며 적합한 변위함수를 이용하여 각 요소의 강도행렬을 구하고 교량상판과 Web 부분의 결합을 조사하였다.
Certain advantages accrue when curved box girders are used for bridges designed to fit curved highway alignments. In addition, if the structure is fitted to the alignment, certain structural efficiencies, such as longer span and shallow depths, are usually obtained.

This study is concerned with the analysis of horizontally curved box-girder bridges. The finite element method of analysis is used with sector and cylindrical shell elements for discretization of flanges and webs of the bridges. The elements have twelve degress of freedom at their nodes and have similar displacement functions which make them compatible. In particular, I investig ated the salient features of interaction between roadway slab and webs as they are important in the finite element method.
