In these thesis, on the basis of existing data collected of arch bridges and dynamics, simply introduce the development and application of the analytical method and finite element numerical analysis method of arch bridges. taking the example of pubugou cfst arch bridge, establish 3 - d finite element model of it with software ansys, and analyze its natural vibration. the effects on inherent vibration of the differences of structure parameters, the restriction of the deck and the effects of different arrangements of cross braces are analyzed
本文在收集有關拱橋及動力學資料的基礎上,分析了拱橋動力學的解析分析法和有限元數值分析方法的優缺點,同時以瀑布溝大橋為背景,使用ansys軟體建立了空間有限元模型,實施了橋跨結構的自振特性分析;並分析了考慮到模型簡化過程中部分結構參數取值差異、橋面板的約束狀況不同等因數對自振特性結果的影響;此外還對橋面上的橫撐布置不同導致對自振特性的影響作了分析。 -
The principles of the general arrangement and the determination of the dimensions of the main structure are described. the dispositions of hangers, outside tie - rods, cross ties, deck - structures as well as the structural analysis and method of construction are discussed in detail, and some opinions about the future development are also given
對橋中吊桿、體外系桿及橫撐、橋面系結構處理、結構力學分析、施工方法等諸方面的技術措施都進行了詳細的論述,並對今後的發展前景提出了一些看法。
