Research on Structural Performance of Prestressed Continuous Rigid Plate Bridge with Different Construction Sequences
Prestressed continuous rigid frame plate girder bridge is less applied and studied in China.This type of bridge structure combines the characteristics of plate girder bridge and rigid frame bridge,suitable for small and medium-sized span bridge structures with longer modular length and multiple spans.Because the structure has a high number of super-static times and more system transformation times during construction,different construction sequences will have a significant impact on the structural mechanical properties.Based on Bar-Boljare Highway Project in Montenegro,in the paper the influence of different construction sequences on the mechanical properties of prestressed continuous rigid plate bridges is studied,which is helpful to the construction progress and cost control in the actual implementation of the project,and has important guiding significance for the design of the structure.
