摘要:
以虎门大桥为研究对象,对车辆轮迹线的横向位置进行了调查和分析,得到了车辆轮迹线的横向位置分布,并给出了相应正态概率分布的设计参数; 采用三维板壳有限元模型分析了车辆轮迹线横向位置分布对正交异性钢桥面板典型构造细节疲劳应力幅的影响,并与欧洲规范和荷兰规范NEN 6788进行了比较。结果表明:采用虎门大桥车辆轮迹线横向位置分布模型计算出的等效应力幅相对较小。
Abstract:
The transverse position statistical distributions of vehicle wheels on orthotropic steel deck were discussed according to investigating data from Humen Bridge, and the design parameters of the corresponding normal probability distribution were given. Influences of acting position of vehicle wheel on fatigue stress range of typical details of orthotropic steel deck were investigated by using 3-D finite element shell model and compared with Eurocode and Holland Code NEN 6788. Results show that equivalent stress range based on the transverse position distribution of Humen bridge is smaller than the others.
