| Abstract: | The finite-element method of SAP2000 can not only calculate the cable force of cable-stayed buckle in the segment installation of basket type arch bridges and provide reliable reference for choosing appropriate buckle cable,but also shows the arch box's stress in each construction stage,which is helpful for the verification during arch box construction,and hence to ensure safety of the arch box. |

| Keywords: | Inclined cable-stayed SAP2000 internal stress of arch box finite-element program |
