中文摘要：

介绍了国内首座CFRP索斜拉桥荷载试验,建立了该桥基于梁壳杆单元的有限元分析模型,进行结构有限元模拟,并与实测结果进行了对比分析.分析结果表明,基于所建模型的结构静力学分析结果与试验结果基本吻合,该模型可用于CFRP索斜拉桥结构的静力学分析.同时,荷载试验结果表明,国内首座CFRP索斜拉桥结构在役刚度和承载能力符合设计要求,整体工作性能良好.文中试验及其相关分析结果可为CFRP新型缆索材料在桥梁工程中的进一步推广应用提供参考依据.

英文摘要：

A load test of the carbon fiber reinforced plastics（CFRP） cable stayed bridge first in China was introduced.A finite element model（FEM） of this bridge,based on beam elements,shell elements and bar elements was established.A finite element analogy of this structure was carried out,and the simulated results were contrasted with test results.The analysis results show that the results of static analysis based on above FEM agree well with experiments,so it is appropriate to use this model in a static analysis of CFRP cable stayed bridge.At the same time,the results of test indicate the stiffness in-service and the carrying capacity of the CFRP cable stayed bridge first in China conform to the specifications and design requirements.The overall performance of this structure is fine.The test and related analysis results provide reference for further engineering applications of CFRP cable bridge structure.
