Mechanical Analysis of Steel Beam and Steel-Concrete Combined Section Pavement in Long-Span Hybrid Girder Bridge

摘要

Firstly the pavement compound system model of steel beam and steel-concrete combined section are established based on structure characteristics of long-span hybrid girder bridge, and the worst loading locations and their characteristics of two beams are obtained. Then, mechanical responses of pavement under the worst loading locations are analyzed to compare mechanical control indices and stress distribution of two beam model. Parameters and suggestions are provided for formulation of standards of long-span hybrid girder bridge pavement, at the same time theoretical basis is and selecting pavement materials and pavement structural optimization design.
