Preface
"Railway Bridge Steel Design Code" TB 10002.2-2005 since the release of China's railway, especially high-speed railway
Construction has made remarkable achievements, the Beijing-Shanghai, Beijing-Guangzhou, Zhengzhou West, Kazakhstan and other high-speed railway, Yi Wan, too Bank of China
Passenger and freight line railway, Shanxi and southern channel, Mongolian and other heavy railways, the Pearl River Delta and Wuhan city circle intercity railway
A large number of railway projects have been completed and opened to traffic, improve the road network structure, an increase of the effective supply of rail transport services. through
Over ten years of active exploration and innovation practice, China's railway bridge construction technology has made a major breakthrough, has been among the world
Advanced ranks. Nanjing Dashengguan Yangtze River Bridge, Wuhan Tianxingzhou Yangtze River Bridge and a number of deep water, large span, special geological
Conditions, the complex structure of the successful construction of the bridge, independent research and development of large tonnage box girder complete sets of technology widely used,
In order to further improve the railway bridge technical standards have accumulated rich experience, laid a solid foundation.
This specification is based on the requirements of the National Railway Administration to build a railway engineering construction standard system, in order to meet the railway bridge construction
Facilities and development needs, unified railway bridge steel design standards, improve the railway bridge steel design level, protection
Railway bridge steel structure safety and quality, on the basis of the original norms, summed up in recent years, China's high-speed, inter-city, passenger and cargo
Collinear and heavy-duty railway bridge steel construction, operation of the practical experience and scientific research, a comprehensive revision.
This specification implements the principles of safety priorities, strengthens quality and safety, conserves resources and protects the environment.
Requirements, focus on the overall design, combined with China's national conditions, socio-economic development level, environmental conditions and other factors, reasonable
To determine the different transport properties of different types of different levels of railway bridge steel structure of the main design standards, to further mention
Rose the norms of scientific and technical economic rationality. In recent years, China's railway steel bridge design field emerged a large number of new
Materials, new structures, new processes, including the use of new materials for Q500q steel, all welded joints and integral steel bridge panels
With the construction of kilometer railway cable-stayed bridge and suspension bridge, the norms in the summary, to absorb the advanced achievements and mature
Experience based on the revised.
This specification consists of 10 chapters, including general principles, terms and symbols, materials and basic allowable stresses, structural forces
Calculate the length of the bar, slenderness ratio and component cross-section, component connection, deck system and joint system, steel beam, steel
Truss beams, bearings, etc., and another three appendix.
The main technical contents of this revision are as follows.
1. Revised the scope of application of the specification, applicable to high-speed railway, inter-city railway, passenger and freight line Ⅰ and Ⅱ railway,
Structural Design of Heavy Haul Railway Bridge.
2. Increase the relevant provisions of Q500q steel.
3. With the national standard "structural steel for bridge" revision, revised steel structure of the steel structure of the relevant provisions.
4. Revised the design requirements for the impact toughness of welded joints (including weld metal and heat affected zones).
5. Increases the fatigue resistance of the 17 structural details; the supplement provides for both axial and bending stresses
Calculation of stress amplitude of rods.
6. The two-line coefficient to expand the formation of multi-line coefficient; added high-speed railway, intercity railway fatigue damage correction system
The ratio of the stress ratio to the correction coefficient table increases the ratio of the stress ratio.
7. Added the relevant provisions for the stability of the box bar with stiffener.
8. The relevant provisions for the effective width of the flange of the bridge deck of the steel truss girder are added.
9. Added the relevant requirements for the effect of the discontinuity of the temperature change on the structure of the truss composite structure.
In the implementation of the norms of the process, I hope the units combined with engineering practice, conscientiously sum up experience, the accumulation of information. Such as
Found to need to modify and add the place, please send the views and relevant information to the China Railway Bridge Survey and Design Institute Limited
