| Abstract: |
Composite beam bridges have been widely used in the main girders of cable-stayed bridges for their excellent performance. In order to study how to apply steel concrete composite girders and concrete π girders in single-tower cable-stayed bridges, the study explores the design technology of hybrid composite beam single-tower cable-stayed bridges based on Shouying Huaihe River Spe- cial Bridge of Hezhou Expressway. Through finite element analysis, a series of parametric analysis of the overall performance of the hybrid composite beam single-tower cable-stayed bridge is car- ried out to study the structural characteristics and analyze the rationality and economy of the structure. The result shows that the hybrid composite beam is a kind of single-tower cable-stayed bridge structure that can well adapt to the asymmetric span distribution with a large proportion of side and middle spans. The research results can provide support and guidance for the background engineering construction and help promote the application of the structural form. |
