| Abstract: | Undue deflection at midspan is one of the common hazards on long-span continuous rigid-frame bridge.In this paper,several influence parameters on long-term deflection of long-span continuous rigid-frame bridge have been analysed,some suggestions and methods are given for reference.A continuous rigid-frame bridge with span arrangement 55 m+100 m+55 m on Hunan Province Jicha highway was selected as the engineering background. |
