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 on the long-span steel bridge is evaluated in three calculation stages. The emphasis of the analysis includes the mechanical characteristics and the influential factors of large components(cross diaphragm)and local components (U-shaped ribs). Considering the mechanical changes by the load of heavy-duty vehicles and heavy load with braking, the interfacial shear failure is studied for the main form of damage. In view of this major form of damage, this paper puts forward the corresponding mechanical analysis of the indicators.

Houdingxiang No. 3 Bridge is a 4-span steel box girder bridge. After the incremental launching construction, the bridge has to be lowering to the support bear, the lowering construction is divided into three stages. At first the launching equipment is used to lower 80cm, the next the jack with load capacity of 180 tons is used to lower 110cm, finally three-direction-jack with load capacity of 200 tons is used to lower 20cm. mechanical analysis on lowering the bridge used jacks with the load capacity of 180 tons and 200 tons is respectively carried out by FEM software ABAQUS, and the result shows that this kind of lowering technique is safe and reliable, it meets the construction demand.

The industry foundation classes (IFC) data model is the most important data schema in ensuring the interoperability of the information generated throughout the lifecycle of facilities. However, because the current IFC model is focused on buildings, there are limitations when this model is applied to bridge structures. This paper proposes a method that enables the information modeling of steel box girder bridges based on the current IFC. To select the required and core items, we classify the components of a steel box girder bridge by the design stage with reference to engineering documents. To generate functional meanings of each bridge component, we develop the rules of the unique identifier and information reassignment, and then apply a semi-automated naming algorithm. The generated bridge information model was used to confirm the functional semantic meanings of individual components, and it was checked whether additional external information, such as carbon emissions, could be linked for specific bridge components. It was observed that information retrieval and extraction for components is possible through a semantic-based query to the generated IFC-based bridge information model.
