【摘要】：基于不同角度,對公路鋼結(jié)構(gòu)橋梁抗疲勞的設(shè)計(jì)進(jìn)行了分析。在公路當(dāng)中承受較多載荷的地方就是鋼結(jié)構(gòu),其中的載荷主要有汽車的恒載以及沖擊載荷和其他情況的載荷等等。從日常的使用當(dāng)中我們能夠發(fā)現(xiàn)許多問題,同時也存在一定的隱患,因此對于橋梁的優(yōu)化設(shè)計(jì)以及抗疲勞的完善是很有必要的。以公路上橋梁結(jié)構(gòu)受到的疲勞影響作為一個主要的因素,綜合分析比較不同疲勞抗力設(shè)計(jì)方法,得出由于荷載差異,對構(gòu)件構(gòu)造細(xì)節(jié)進(jìn)行驗(yàn)算,不斷對橋梁抗疲勞結(jié)構(gòu)設(shè)計(jì)方法進(jìn)行優(yōu)化,提高橋梁可靠性和安全性。
[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.
