• Global bridge model
• Local box girder model
• Orthotropic steel deck
• Surfacing

A kind of new global-local model is proposed to study the steel bridge deck surfacing system. Three dimensional finite element model of the global bridge, local box-girder and local orthotropic steel deck are set up separately, then the static calculation results of the global bridge are transferred to the model of the local orthotropic steel deck through the setup of boundary conditions. The research results show that the maximum, longitudinal tensile stress of surfacing calculated in view of bridge type of suspension is 12.6% more than the old research results. The mechanical analysis method proposed is more close to the actual work condition of the steel deck surfacing.
