某在役铆接钢桁梁桥关键构件疲劳性能研究
摘要
Abstract
Accurate evaluation of the fatigue life of steel bridges in service is very important for the safe operation of bridge structures.In this paper,a riveted steel truss bridge in service is taken as the research object.Based on the calculation and analysis of the bridge structure and the mechanical characteristics of each member,a series of fatigue performance studies are carried out for the typical members and key joints of the original bridge.The numerical results show that the typical members and key joints of the original bridge under city B load have good anti-fatigue performance,and the number of fatigue life cycles is more than 2 million.关键词
