Mechanical Analysis of Steel Bridge Pavement

Pavement on bridge is an important part of vehicle system, if plays an important role in bridge durability,vehicle safety and comfortable level but also in economic benefit and social benefit.And it is a key point in constructing long-span bridge. This kind of technology if also a worldwide problem. The finite element model is established in this paper uniting the orthotropic steel deck and pavement, and the avriation of tensile stress in the surface for a typical steel deck surface system is analyzed. The researches provide the theoretic basis for the design and study of steel deck bridge pavement.
