ADINA在双河口大桥动力特性模拟分析
|
摘要
采用ADINA软件,建立双河口连续刚构桥的三维空间有限元模型,对双河口大桥的动力特性进行数值模拟分析与计算,得出双和口大桥典型工况下的自振频率及振型,为该桥结构抗风以及抗震设计分析等提供必要的依据。计算研究结果为今后在实际工作中遇到类似情况提供一种有意义的、经验性的指导。
To adopt software ADINA and establish model of three dimensional space finite element in order to make numerical simulating analysis and calculation of dynamic characteristics of shuanghekou bridge,obtaining the natural frequency of vibration and the vibrating mode,which provide necessary basis for analyzing the design in wind-resistance and seism-resistance of present bridge's structures.The results of computating study offer a significant and experienced instructions for settling the simular issues coming across in practical project in future.
