ケーブル構造の形状決定に関する一計算法

抄録

A cable element has been developed in our papers for flexible cable structures with pulley. This element is formulated by modified functional of variational principle and has the same features as usual finite element based on the displacement method in which displacements are unknown variables. In this paper some functions are appended for shape finding of many cable structures such as cable net, suspension bridge and cable stayed bridge. Some numerical examples are to show the accuracy and efficiency of the proposed numerical method.
