| Abstract: | With the rapid development of long-span prestressed concrete beam bridge, the analysis and calculating of shrinkage and creep influence on bridge concerned deeply by structural designers, therefore creep theory and calculating method obtained increasing development. This article summarized each creep analytical method, using integral degenerate check method to compute long-span prestressed concrete continuous frame bridge, some valuable conclusions were obtained, which could be useful considerations for bridge design. |
