Abstract：In order to precisely impose the constant load initial cable force for cable stayed bridge, an iteration imposed method for cable force through controlling temperature based on the ANSYS platform was proposed,and thus the initial cable force of cable stayed bridge could be precisely applied at the completed stage of the bridge. The design cable force was taken as the target value,the geometric nonlinear factors of cable stayed bridge were considered,and the initial cable force was imposed to the cable stayed bridge in the form of initial temperature. The iterative calculation program for the cable force of cable stayed bridge at the completed stage was compiled with the APDL two-developed software,and the program was applied to the structure analysis of twin tower double cable plane steel-concrete composite girder cable stayed bridge. The results show that the errors of both calculated and target cable forces for the stayed cable on both sides of bridge tower are within 5%. Therefore, the iteration method for initial cable force has the advantages including the convenience and shortcut as well as high efficiency.
