| 摘 要： | 推导出薄壁高桥墩自振频率的计算公式，并将该公式计算结果与有限单元法计算值进行了分析与比较。在用瑞利里兹法和有限元法计算墩顶水平位移的同时，对由竖向荷载作用所产生的几何非线性对墩顶水平位移的影响作了初步分析。

| Abstract: | Equivalent stiffness method proposed by the authors is used to calculate free-vibration of thin high bridge piers,then the result of calculation is analyzed and compared with that of FEA method.The influence of geometric non-liner problems caused by vertical force on lateral displacement at the top of the pier is also discussed when it is computed by the Rayleigh-Ritz method and FEA method. |

| Keywords: | higher bridge pier free-vibration frequency lateral displacement the geometric non-liner energy method |
