CFRP螺纹锚具在吊杆拱桥中应用试验研究

Research on application experiment of CFRP screw anchorage in suspender arch bridges

结合某实桥,按照相似原理,建立了碳纤维吊系杆拱桥缩尺试验模型,试验对其使用阶段两种工况受力进行模拟加载,并运用Midas/Civil有限元分析软件对其进行建模和模拟使用阶段受力,得出理论数值。拟通过实测值与理论值的对比,对其进行受力性能的分析,以此来检验CFRP螺纹锚具在吊杆拱桥中应用的可靠性。

Combining some bridge, the paper establishes the subscaled experimental model of the carbon fiber suspending arch bridge, under- takes the loading simulation on the stress of two construction conditions in the application stage during the experiment, establishes the models and simulates the stress in the application stage by adopting Midas/Civil finite element analyzing software, concludes the theoretic numeric value, and has the analysis of the stressed performance by comparing the measured value and the theoretic value, so as to test the reliability of the CFRP screw anchorage in susvender arch brid^es.
