ABSTRACT
ABSTRACT: Design parameters of the fatigue test specimen of the Zhijiang Bridge in Hang Zhou City, such as boundary conditions, diaphragm height, deck plate width and the number of U-rib, were investigated by FEM. Analysis results of try test specimens were compared with that of full bridge analysis model with framed finite elements and substructure of shell elements. The influence of different design parameters on the stress distribution of fatigue specimen models was studied and the value ranges of design parameters were discussed.
