| Abstract: |
The erecting analysis of cable-stayed bridges involves repeatedly modeling to sequential structural systems, in which substructure procedures is accomplished. A single tower cable-stayed bridge of rigid connection between girder, tower and pier is used as an example to illustrate the rules of substructure division and to perform the analysis of erecting stages. The erecting stages are simulated by 30 super-elements of successive mode. The calculating results show that the time consumption of substructure procedures is just one seventh of that by ordinary method with the comparative accuracy of both methods not exceeding 5%. Thereby, it is confirmed that substructure procedures are applicable to the erecting analysis of cable-stayed bridges with obvious advantages. |
