| 摘 要： | 为确定使用15年后永和斜拉桥破损诊断所需要的“参考基”，该文建立了双索面通过刚臂与主梁及边梁相连的三梁式力学模型，采用ANSYS结构分析程序对永和斜拉桥进行动力分析，对其振动模态参数（频率、振型及阻尼）进行识别，与动力测试结果进行对照表明，该文计算结果可作为斜拉桥完好状态下的动力“指纹”；该结果为永和斜拉桥养护维修方案提供了技术支持，具有理论与实用价值。

| Abstract: | In order to define thereference baserequired for the breaking diagnosis of Yonghe Ca- ble-stayed Bridge after 15 years,the article sets up the double-plane 3-beam mechanical model through connecting the rigid ann with the main beam and side beam.ANSYS structural analysis program is used to carry out the dynamic analysis of Yonghe Cable-stayed Bridge,to distinguish its vibrating modal parameters (frequency,vibrating type and damping),and to compare with the dynamic test result.The calculation result in the a... |
