| 摘 要： | 针对鞍座上主缆与主塔的连接方式，建立两个有限元模型，分别采用固定铰接和活动铰接的方式，对它们进行静动力分析，考察不同鞍座边界条件对悬索桥静动力特性的影响特点和程度，并通过试验模型的实测数据对两模型精度进行评定，对悬索桥有限元建模具有参考价值和指导意义。

| Abstract: | According to the connection form of cable and tower, two finite dement models have been built. The static and dynamic properties have been analyzed by using fixed and active articulated modes separately. In this paper, the characteristics and degrees of influence on static and dynamic properties of suspension bridge have been studied in different saddle botmdary conditions, and the accuracy of two finite dement models have also been assessed compared with the test data. It is of reference value and guidance for finite element modeling of suspension bridges. |
