摘要
桥梁结构的疲劳问题是其结构设计中的一个关键问题。本文介绍了从德国人设计第一台疲劳试验机开始研究金属疲劳问题到形成桥梁结构疲劳设计规范整个桥梁结构疲劳特性分析发展历程 ,同时也较详细地介绍了桥梁结构的一般抗疲劳评定方法和抗疲劳设计方法。
Fatigue is a key problem in design of bridge structures. This paper introduces the analysis and development history of fatigue properties of bridge structures,ranging from the first fatigue tester designed by German,which was used for researches of fatigue of metals,to establishment of fatigue design criterion of bridges. Meanwhile,it gives detailed descriptions of the general anti-fatigue assessment and design methods of bridge structures.
