词语大全 stayed-cable中文翻譯

Process in the anasyis method of wind - induced vibration for long span stayed - cable bridge
大跨度斜拉橋風振響應研究進展

This paper summarizes the research situation of the static and dynamic characterizes of stay - cables , estabpshes the finite element model of stay - cables based on matlab , and analyzes on the model with actual example
綜述了斜拉索靜動力特性的研究情況,建立了基于matlab的斜拉索有限元模型,并通過實例對模型進行了分析。

As a result , while some stayed - cables are released , the cable forces of remaining and neighboring 2 or 3 groups increase remarkably , but the others do not , the box - girder puts up the characteristic of biggish stiffness which stress variety is n \' t marked
對該橋換索不同工況的計算結果表明：卸索后的索力基本由同側、同號剩余索和臨近2 3組斜拉索所分擔；主梁剛度較大，各工況主梁彎曲應力變化并不顯著。

Aiming at main project of the xiaoxihu bridge , a low pylon cable - stayed bridge , based on the existing theory and method of the bridge construction controlpng theory , using the basic function of " ansys " , farther exploitation was done on concrete elasticity and creep calculating distinguishingly , nonpnearity analysis theory was used to construct the space model , the main beam , string pylon and abutment were simulated by the beam elements which was considered the shearing effect . which is worthy of considering that using the geometric non - pnear truss elements to simulate the stayed - cable , form traveler is modeled as structure elements and participate in stress analysis . four stages are used to model the construction stage , which are : ( 1 ) the erection of form traveler ; ( 2 ) placing the segmental concrete ; ( 3 ) jacking the tendons ; ( 4 ) tensioning the stay cables
針對建設中的小西湖矮塔斜拉橋的主體工程，結合已有的橋梁施工控制的理論和方法，利用大型通用計算軟件ansys的基本功能，并著重在混凝土彈性計算及徐變計算方面做了相應的二次開發，采用非線性分析理論并建立了空間結構模型、用考慮剪切作用的梁單元模擬主梁、索塔和橋墩；用可考慮幾何非線性的桁元模擬斜拉索、施工掛藍作為結構單元進行拆裝，參與受力計算，整個施工過程按施工循環周期分為若干階段，每個階段又分為四個工況，即：空掛藍就位、澆筑完畢階段混凝土、張拉預應力鋼筋和張拉斜拉索。
