  • In order to research the change law of non-linear stability and its influencing factors of a long-span composite cable-stayed bridge during construction, by taking Edong Yangtze River bridge as research subject, LSB and ANSYS models were built based on the structure type and construction sequence of the bridge to calculate the non-linear stability safety factors during bridge construction and obtain the instability mode. The influencing law of non-linear factors to static stability was analyzed. In addition, the relationships among the stability during construction and steel-concrete connection position, cable-beam anchorage mode, temporary construction loads and cross-wind load were investigated. The research results show that the above factors have different effects on the stability during construction, but they are not controlling factors.
