| 摘 要： | 以某自锚式悬索桥主桥为研究对象,采用M IDAS有限元程序,建立了该桥的空间力学计算模型,利用子空间迭代法计算了该桥梁结构的自振频率和振型,结合计算结果对桥梁的动力特性和刚度特点进行了讨论。计算结果可为该类型桥梁的设计、施工以及使用阶段的健康检测和维护提供技术参数和依据。 |

| Abstract: | One self-anchored suspension bridge is the subject investigated,the finite element program "MIDAS" is adopted to establish the spatial computation model of the suspension bridge,and the subspace iteration method is used to calculate the natural vibration frequencies and modes of the bridge,the bridge's dynamic property and rigidity feature are discussed with the computed results.The results can supply technical parameters for the design,construction,health detection and maintenance in the operational phase of the bridge. |
| Keywords: | self-anchored suspension bridge dynamic performance mode natural frequency |
