| Abstract: | Stacked tied arch bridge is a new bridge system. The system is used to design scheme of a bridge. Through the overall design of a stacked concrete-filled steel-tabular tied arch bridge, the rational combination of the rise-span ratios is investigated. Then the design of spans arrangement, the longitudinal girders, the cross girders, the tied members, the hangers and transverse braces are introduced. Finally, the structural and mechanical characteristics of stacked tied arch bridge are investigated. |
