“…During the operation of the transmission lines, ACSR can maintain a certain spatial shape after being pulled at the end along the axial direction [5]. Therefore, it has a certain bending rigidity, and the bending rigidity is closely related to the magnitude of the axial force [6]. Li et al [7] researched the mechanical characteristics of the ACSR under axial load, and used the equivalent rigidity to solve the parameters such as the elastic modulus and Poisson's ratio of the ACSR.…”

The dynamic bending rigidity of aluminium cable steel reinforced (ACSR) is a key parameter for analyzing the breeze vibration, galloping and de-icing vibration response of overhead transmission lines. In this paper, the calculation formula of the dynamic bending rigidity under axial force is derived based on the theory of Bernoulli-Euler beam. The dynamic response of one typical ACSR with different spans and different axial forces are studied by white-noise excitation and hammer excitation. The variation rules of dynamic bending rigidity of ACSR are presented. The comparison between the experimental results of the static and dynamic bending rigidity shows that the dynamic bending rigidity of the ACSR is much larger than the static bending rigidity.

“…Three types of element have been mainly adopted: 1) straight element, 2) curved element, and 3) curved element with rotational degrees of freedom. Baron and Venkatesan (1971) developed the stiffness matrix of a three-dimensional two-node straight truss element including the effect of stress stiffening. They used the direct stiffness method and a nonlinear iterative scheme to solve cable structures subjected to static concentrated forces.…”

A finite element analysis technology applicable to the prediction of the static nonlinear response of cable roof structure is presented. The unified kinematic description is employed to formulate the present cable element and different strain definitions such as Green-Lagrange strain, Biot strain and Hencky strain can be adopted. The Newton-Raphson method is used to trace the nonlinear loaddisplacement path. In the iteration process, the compressive stress of a cable element is not allowed. For the verification of the present cable element, four numerical examples are tackled. Finally, numerical results obtained by using the present cable element are provided as new benchmark test results for cable structures under static loads.
