tie beam

The main structure of caiyuanba yangtze bridge in chongqing , up to date the largest - span tie bar arch bridge , is formed by two side tie bars and one middle tie bar which unite the y - shape rigid framework and arch rid . therefore , tie bars are one of the key components 重慶菜園壩長江大橋是迄今為止世界上跨度最長的系桿拱橋,該橋的兩根邊系桿和一根中系桿將南北兩岸的y型剛構和中間的拱肋連成一個受力整體,構成該橋的主結構,因此系桿是該橋關鍵受力部位構件之一。

3 ) based upon analyzing the variation laws of bridge ’ s dynamic features , it is proposed in this paper that structure frequency and mode of vibration should not be used as the “ dynamic index ” of cable force dynamic evaluation , because the variation of structure frequency and mode of vibration resulting from tie bars ’ loss is very small 3 )在分析系桿截面損失時橋梁整體結構的動力特性變化規律的基礎上,指出系桿損失引起的整體結構頻率及振型的變化很小,不宜作為索力動態評估的“動力指紋” 。

The software ansys6 . 0 is used to analysis the stability of the state after construction of tongwamen bridge , linear method is used in analyzing the finite element model of the bridge , the coeffient of stability of different state after construction is given . on the basis , the effect of different factors such as the arrangement of lateral brace , the sloping angle of arch ribs , the stiffness of bridge deck system , the effect of non - orientedly conservative loadings of the hanger and tie bar etc is discussed . the different coefficients of stability of changing these factors are given , so the factors that are vital to the lateral stability of x - type arches are found , and the rationality of the methods taken to enhance the lateral stability of tongwamen bridge is evaluated 本文應用有限元分析商業軟件ansys6 . 0 ,采用線彈性方法,通過對該橋的空間有限元模型進行穩定性分析,得出其成橋運營階段各種工況下的穩定安全系數。在此基礎上,本文還通過有限元模型分析,就拱的矢跨比、吊桿(立柱)的非保向力效應、橋面系的剛度、橫撐布置形式、拱肋側傾角等因素對該橋整體穩定性的影響展開探討與研究。文中給出了各因素變化情況下的穩定安全系數,指出了對鋼管混凝土提籃拱橫向穩定性有顯著影響的因素及其合理變化范圍,并對銅瓦門大橋提高橫向穩定性的措施的經濟合理性進行了分析。

The content of this research mainly include : 1 ) with the increasing loss of tie bars ’ sections , variation laws of cable force , internal force and displacements in each monitoring spots are analyzed on work conditions of constant load , light rail , automobiles and temperature . on this basis , the evaluating indexes of safety state of tie bars are determined 主要研究內容為: 1 )分析了恒載、輕軌、汽車和溫度作用工況下,隨著系桿截面損失的增大,系桿索力和橋梁各監測點內力及位移的變化規律,確定了評估系桿安全狀態的評估指標。

2 ) on the basis of calculation , evaluation indexes are quantified according to the following four conditions : normal state , regular observation , regular warning and urgent warning . then , the static evaluation threshold value of tie bar is preliminarily determined 2 )在計算分析的基礎上,將系桿安全評估指標按正常狀態、一般觀察、一般預警和嚴重預警四種狀態進行量化,初步確定系桿監測系統的靜態評估閾值。

Based on caiyuanba yangtze bridge project , the static and dynamic evaluating indexes and threshold values of tie bars are analyzed in this paper , which aims to provide an important reference data for the safety evaluation scheme of the bridge 本文以重慶菜園壩長江大橋為工程背景,討論了該橋系桿的靜、動態評估指標及其閾值,為橋梁安全評估方案的確定提供重要的參考依據。

On the basis , the effect of different factors such as the sloping angle of arch ribs , the stiffness of bridge deck system , the effect of non - orientedly conservative loadings of the hanger and tie bar etc is discussed 此外,采用線彈性方法,就拱的吊桿的非保向力效應、橋面系的剛度、橫撐布置形式、拱肋側傾角等因素對該橋整體穩定性的影響展開探討與研究。

This paper is mainly concerned with the structural characteristics and research process of fiber grating strain sensors , successful applications of strain sensors in the bowstring arch bridge , particularly the tie bar cable replacement 文中介紹光纖光柵測力傳感器的結構特點和研究過程,及其在系桿拱橋換索施工中的成功應用。

In this paper , the stubble , rust of tie bars and destruction forms of anchorage device are considered equivalent to the loss of tie bars ’ sections which is the analysis parameter of this paper 本文將系桿的斷絲、銹蝕及錨具等破壞形式等效為系桿截面的損失。
