摘要:
通过模型试验对9根索股进行静动力测试,分析抗弯刚度对悬索的自振频率及变形的影响; 介绍了试验模型的设计方法、相似原则以及加载方案,对主缆抗弯刚度的计算值与测量值进行了对比。结果表明:悬索的抗弯刚度对悬索的自振频率影响较大,特别是对高阶频率; 抗弯刚度对悬索的静力变形影响主要位于靠近桥塔的位置,且随着索股钢丝数的增多,影响变小。
Abstract:
Static and dynamic testing of nine strands was carried out by model tests, bending stiffnesses on the natural frequencies and deformations of the suspension cable were analyzed. The design method of test model, scaling rules, and loading programs was introduced, and the calculated and measured results of bending stiffness of main cable were compared. The results show that the bending stiffness produces a greater effect on the natural frequency of suspension cable, especially in the high frequency. The influence of the static deformation with bending stiffness is mainly located near the location of the bridge towers, and with the increase in the number of strand wire, the influence of the bending stiffness decreases.
