Abstract

본 연구에서는 고정하중을 받는 다경간 현수교의 예비해석을 위한 케이블 부재의 초기평형상태 해석방법을 제안한다. 본 연구에서 제안한 초기 평형상태 해석 알고리즘은 타 연구들에서 사용된 기존 방법들보다 간편하고 실용적이며, 3경간 현수교 및 다경간 현수교에 적용 가능하다. 제안방법의 타당성을 검증하기 위해, 3경간 현수교 예제모델과 4경간 현수교인 국내의 새천년대교 및 중국의 Yingwuzhou Bridge 모델을 사용하여 초기평형상태 해석을 수행하였다. 검증 결과, 본 연구에서 제안한 초기평형상태 해석방법에 의한 결과가 3경간 예제모델의 선행 연구결과 및 새천년대교의 설계값과 잘 일치하는 경향을 나타내었으며, 제안 방법은 Yingwuzhou Bridge에 대한 초기형상을 잘 유지하는 초기값들을 도출하였다. This paper proposes a method to determine the initial equilibrium state of cable members for preliminary analysis of multi-span suspension bridge under dead load. The proposed method is simpler and more practical than the previous methods used in other studies. The proposed method can be applied to three-span or multi-span suspension bridges. To verify the proposed method, an three-span model as well as four-span models such as New Millenium Bridge in Korea and Yingwuzhou Bridge in China are analyzed. In the verification results, the initial coordinates and tensions of the members calculated by the proposed method are good agreement with those in the previous study for the three-span model and those in the design data of New Millenium Bridge. In addition, the proposed method gives the initial values to keep the initial configuration of Yingwuzhou Bridge.
