The ultimate span length of cable-stayed bridge has been an interesting issue among bridge engineers for a long time. Although knowledge about the span limitation is growing, little is known about the difference of structural mechanical performances among cable-stayed bridges with even larger spans. Four bridges with main span length from 1,000 to 2,500m were preliminarily designed and calculated, with their components and main parameters adopted based on existing long-span cable-stayed bridges such as Sutong Bridge. The bridge models with the spans from 1,000m to 2,000m can meet requirements of strength, rigidity and stability, but in-plane stability of the 2,500m model can not be ensured.
