The objective of the research presented here is to develop a determination of cable tension for cable structures basing on proposed cable element with pulley by using some constraint conditions. First, known horizontal component of cable tension is assumed to be equal at position of intersection between cable and tower. Secondly, displacement of girder is supposed to be minimized at position in which the girder is supported by cable. These conditions are reasonable because it is considered that

With proposed procedures, even if a special calculation technique for finding shape is not used, shape-finding and structural analysis for cable structures could be done with the same technique. The results of the method are compared with those of the conventional one in the application of some numerical examples of cable-stayed bridge to show the accuracy and efficiency of the proposed shape-finding method.
