Research on Analysis Method for the Saddles of Long-span Suspension Bridges with CFRP Cables
为了深入研究碳纤维增强树脂(CFRP)缆索悬索桥主索鞍的合理设计参数,首先介绍了复合材料的Tsai-Hill失效准则,并利用解析法推导了主缆在主索鞍处的弯矩估算公式,在此基础上提出了一套关于CFRP缆索悬索桥主索鞍的设计计算方法.然后利用该方法对CFRP主缆上的索鞍性能指标进行了参数分析,研究了主缆丝股直径、索夹间距、索鞍半径、CFRP-钢摩擦系数等设计参数对索鞍受力性能的影响.结果表明:通过减小丝股直径、增大索夹间距、增加索鞍半径等措施,可显著…查看全部>>
In order to further study the proper design parameters for the saddles of suspension bridges with carbon fiber reinforced polymer (CFRP) cables,the Tsai-Hill failure criterion was firstly introduced,and the formulas for the cable moment at the saddles was derived,based on which the analysis method for the saddles of CFRP suspension bridges was proposed.Then,a parametric study on the mechanical indexes of saddles on the CFRP cable was conducted,where the infl…查看全部>>
