Global Stress Analysis and Discussion of Large-Span Prestressed Concrete Bridge with Rigid Frame - Continuous Girders

On the base of test of plexiglass model and the loading test of a large-span prestressed concrete bridge with rigid frame-continuous structure, differences between the bridge with rigid frame-continuous girders and continuous bridge and continuous rigid frame bridge are compared and analysed. The force characteristics and structural behaior of large-span prestressed concrete bridges with rigid frame-continuous structure are studied. It offers an important reference to the perfection for design theory and construction technology of large-span prestressed concrete bridge with rigid frame - continuous girders.
