Experimental Research on Segmental Model of Girder for Binzhou Yellow River Bridge
Binzhou Yellow River Bridge is a four-span cable-stayed bridge with prestressed concrete girders. To ensure the integrity of the girder and resist transverse bending due to dead load and service load, transverse prestressing tendons were disposed in the diaphragms. During the in-situ experiment for full-scale segmental model of the girder, stresses and cracks on one oblique web of the side-boxes were measured. Through mechanical analysis for segmental model of the girder by spatial finite element method (FEM), the mechanism of the two oblique webs under transverse prestressing was obtained. Further analysis showed that improving methods such as adding prestressed strands and reinforced bars were available to distribute high stress concentration and avoid cracking of concrete.
