The space frame lattice model, which is suitable for
the analysis of stress of entire cross-section of
bridge, is presented. It is suitable for the
analysis of stress of entire cross-section of bridge.
The relatively weaker position of stress in
box-girder section was analyzed. By using the
presented space frame lattice model, the shear
stress and principle tensile stress of the box
girder cross-section in Xintan Bridge, which is a
continuous prestressed concrete rigid frame with the
75+130+75 m span, was calculated and analyzed. An
innovative layout method of mixed internal and
external prestressed tendons was adopted. In
addition, the space frame lattice model is worth to
be further investigated. It can be applied to more
bridge patterns. |
