高墩抗震性能指标与分析模型精细度的关联性研究

Research on relevance of seismic performance indexes and model accuracy of high pier

使用大型有限元分析软件ADINA对高墩进行非线性时程分析,通过对模型采用不同积分段划分形式,研究高墩抗震性能指标与模型精细度的关联性,探讨如何选择与模型关联性小的性能指标,并给出合理划分单元的建议,所得结论可为桥梁抗震设计提供参考.

This paper studied the relevance of the seismic performance indexes and the model accuracy of high pier in the case of different divisions of the model, using the large finite element analysis software ADINA by the nonlinear time-history analysis. How to choose the minimum relevance performance indexes was discussed, and a reasonable advice of element division was given, the reference for the bridge seismic design is provided.
