To address the possible deviations in component fabrication and installation during the construction process,a sensitivity analysis of the cable system roof structure of the Leshan Stadium was conducted.Considering cable length errors,cable clamp installation errors,and support installation errors,the sensitivity of structural errors under maximum and random error conditions was analyzed.The displacement and deviation of cable forces under different error conditions were examined.It was found that the overall structure was not highly sensitive to errors.The impact of cable clamp and support installation errors on the structure can be negligible.The cable length error has a certain degree of influence on cable forces in the structure and should be controlled particularly.
