Abstract

The invention provides an orthotropic steel bridge deck slab structure. The orthotropic steel bridge deck slab structure comprises a roof, a multi-U-shaped plate and cross partition plates. The continuous multi-U-shaped plate has the characteristics of good integrity and large stiffness, and the problem of excessive local deformation of a steel bridge deck slab under the effect of the concentratedwheel load can be effectively avoided. When the high strength bolt connection mode is adopted instead of the welding connection mode, the fatigue resistance is better, the technological requirement is low, and meanwhile the orthotropic steel bridge deck slab structure can serve as a shear connecting piece to reinforce the joint effect between a bridge deck pavement layer and the steel bridge deckslab. The orthotropic steel bridge deck slab structure is simple in structure, reasonable in design, good in fatigue resistance and convenient to manufacture, construct, repair and reinforce, and haswide application prospects in the field of steel structure and composite structure bridge engineering.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to an orthotropic steel bridge deck structure. Background technique [0002] The orthotropic steel bridge deck (hereinafter referred to as "steel bridge deck") is a structural form that is composed of mutually perpendicular top plates, longitudinal ribs and transverse diaphragms (transverse diaphragms) connected by welds and working together. It has light weight, It has the characteristics of large bearing capacity, wide application range, fast construction speed and beautiful appearance. In 1950, Germany built the first Kufalz bridge explicitly using orthotropic slabs as the bridge deck. After half a century of development, orthotropic slabs have become the main deck structure used in large and medium-span steel bridges at home and abroad. [0003] With the wide application of steel bridge decks and the continuous increase in service time, in recent years, there have b...
