Abstract

At present, there are few studies on the construction error sensitivity of superimposed beams, the cause of error prediction, the change of error, and error propagation pathways. To improve this situation, this paper selected the asymmetric steel-concrete superimposed beam cable-stayed bridge, namely Yibin Nanxi Yangtze River Bridge as the support project and used the finite element analysis software to simulate the whole process of the bridge considering geometric nonlinear construction. On the premise that the sensitivity parameters in the construction process cannot be completely accurate, the influencing factors and formation mechanism of the main beam installation error were analyzed, and the alignment and stress change of the main beam with the construction stage were studied. The propagation law of the main beam installation error was revealed, which provided a theoretical basis for the determination of the allowable error and the optimal adjustment strategy of the error.
