| Abstract: | A cable finite element is proposed in this paper. The element is very suitable for the calculation of construction control in long-span cable-stayed bridges and can easily deal with the eccentricity of anchored joints. The element stiffness matrix and the equivalent nodal-load vector for tensioning the cable element are derived. Several special problems and imitating skills for a cable-stayed bridge in process of the con- struction control are described. The reliability and wide applicability of proposed method are verified by experimental results of a real bridge. |
