【摘要】：基于不同角度,对公路钢结构桥梁抗疲劳的设计进行了分析。在公路当中承受较多载荷的地方就是钢结构,其中的载荷主要有汽车的恒载以及冲击载荷和其他情况的载荷等等。从日常的使用当中我们能够发现许多问题,同时也存在一定的隐患,因此对于桥梁的优化设计以及抗疲劳的完善是很有必要的。以公路上桥梁结构受到的疲劳影响作为一个主要的因素,综合分析比较不同疲劳抗力设计方法,得出由于荷载差异,对构件构造细节进行验算,不断对桥梁抗疲劳结构设计方法进行优化,提高桥梁可靠性和安全性。
[Abstract]:Based on different angles, the fatigue resistance design of highway steel bridge is analyzed. The steel structure is the place that bears more loads in the highway. The loads mainly include the dead load of the automobile, the impact load and other loads and so on. From the daily use we can find a lot of problems at the same time there are some hidden dangers so it is necessary for the optimization of bridge design and the improvement of anti-fatigue. Taking the fatigue effect of bridge structure on highway as one of the main factors, this paper comprehensively analyzes and compares different design methods of fatigue resistance, and concludes that due to the difference of load, the structural details of members are checked and calculated. In order to improve the reliability and safety of bridge, the design method of anti-fatigue structure has been optimized.
