摘要

The mechanical analysis is applied for the steel box girder bridge with orthotropic plate and pavement by means of Finite Element Method. The interaction between steel bridge and pavement is evaluated by the three stages in calculation. The analysis is focused on the mechanical features and the influential factors of the large components (cross diaphragm) and the local components (U-shaped ribs). Considering the mechanical effects by the heavy-duty vehicle load and heavy-load with braking, the interfacial shear failure is studied as one of the main reasons of damages. Moreover, in view of this major form of damage, this paper provides the corresponding mechanical analysis of the indicators.
