새천년대교 건설을 위하여 설치된 공사용 구조물, 작업용 선박 및 바지선 등 새로운 항행장애물 발생으로 인하여 항행여건이 더욱 열악하게 됨으로써 해양사고 발생 가능성이 증가하고 있어 이에 대한 안전대책을 수립 시행하여 해양사고를 예방하고자 한다.

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.
