Wuhu Yangtze River bridge is a new type of railway highway bridge with the longest span and the largest scale in China at the end of 20th century. A series of new technology, new structure style, new steel material and new processing technology, have been used in the design. As one of the key technology research projects of Wuhu Bridge, this article will introduce the fatigue design method and the fatigue model test for some important structural details in Wuhu Bridge. That includes general theory, the design theory and method adopted by Wuhu Bridge, the fatigue test with high tonnage, model description of some details based on the destroyed samples, as well as the results of the fatigue tests. This research achievement was provided promptly to bridge design, and therefore insured the design quality of the bridge and the building time for the project. It was included in the Code for Design on Steel Structure of Railway Bridge TB10002 2 99 issued and implemented in 2000.

To study the reliability of the design of Tianxingzhou Road/rail Yangtze River Bridge, the finite element model of the bridge is built with Ansys, and live load combinations are analyzed, calculated and compared based on its initial state. Element stress under each load combination is calculated based on criterion of steel railway bridge design, through which the worst load combination is found. Five-grade failure tree is generated based on fault analysis algorithm of minimum load increment with the APDL (Ansys...

To study the reliability of the design of Tianxingzhou Road/rail Yangtze River Bridge, the finite element model of the bridge is built with Ansys, and live load combinations are analyzed, calculated and compared based on its initial state. Element stress under each load combination is calculated based on criterion of steel railway bridge design, through which the worst load combination is found. Five-grade failure tree is generated based on fault analysis algorithm of minimum load increment with the APDL (Ansys Parametric Design Language) in data processing. The analysis indicates: The design is reliable, some key elements are very important for the bridge reliability, and reinforcement of those elements would efficiently improve the bridge reliability; and APDL language of Ansys software could be very convenient for model building and data processing of complex structures.

为研究天兴洲公铁两用长江大桥设计方案的可靠性,运用Ansys软件建立大桥的有限元模型,在成桥状态基础上,分析、计算和比较活载的荷载工况,依照铁路桥梁钢结构设计规范计算各工况下杆件的应力,从而得到最危险的荷载工况;以最小荷载增量准则为失效分析理论,利用Ansys的APDL参数化设计语言进行后处理,生成大桥前五级失效历程的失效树。分析结果表明:该大桥设计方案可靠性较高;某些关键杆件对桥梁的可靠性尤其重要,加强这些杆件能高效提高设计方案的可靠性;Ansys软件的APDL参数化设计语言对复杂结构的建模和数据处理尤为方便。
