Influence of different radial stiffener welding to bias-rail box girder on the load capacity of main girder;

Study of local stress of the main web from the bias-rail box girder nearby the trolley wheel pressure

The local stress analysis about the bias-rail box girder based on elastic ground

Overhead traveling crane box-girder optimal design software;

3D parameterized design and finite element analysis of box girder;

Five different finite elementary models are established based on box girder with different thickness of the bottom flange of cable-stayed bridge.

By using the structural analysis program ANSYS,seven finite elements models based on three long-span cable-stayed bridges box girder with different lengths and dimensions have been built up,and the triaxial stress of them are analyzed.
