Scope

1.0.1 This Code is formulated with a view to carry out relevant national laws and
regulations and railway technology policies, unify the technical standards for the
design on steel structure of railway bridges and make the design on steel structure of
railway bridges comply with the requirements of safety and reliability, advance and
mature, economy and usability, and environmental protection.
1.0.2 This Code is applicable to the design on steel structure of riveted, welded-and-
high-strength-bolted and welded bridges for high-speed railways, inter-city railways,
passenger-freight I and II level railways. The steel structure of bridges carrying both
railway and highway which bear the highway load separately shall be designed
according to the relevant standards of the current highway industry.
1.0.3 The steel structure of railway bridges shall have the specified strength, rigidity,
stability and durability. The service life of the main structure shall be 100 years.
1.0.4 When adopting this Code, the design shall still comply with the provisions of the
current “Code for Design on Railway Bridge and Culvert” (TB 10002).
1.0.5 The design on components of steel structures shall be standardized so that the
same type of components can be interchangeable. The structure shall be easy to
process, transport, install, inspect and maintain.
1.0.6 The bridge superstructure shall be provided with camber, and the camber curve
should be basically the same with shape of the deflection curve generated by the dead
load and half static live load, but with the opposite direction. When the vertical
deflection caused by the dead load and static live load is not more than 1/1600 of the
effective span of the bridge, the camber may not be provided.
1.0.7 For bridge superstructures, in the most unfavorable combination of calculated
loads, the lateral tipping stability factor shall not be less than 1.3.
1.0.8 The steel beam shall be able to be lifted by jacks. The lifting facilities and
structures themselves shall be calculated as 1.3 times the lifting load.
1.0.9 For bridges with deviated line center on the curve and other bridges with
eccentric load, the influence of eccentric load on the bridge superstructure shall be
calculated.
1.0.10 For the design on steel structure of railway bridges, not only the requirements
stipulated in this Code, but also those in the current relevant ones of the nation shall
be complied with.
