摘要
利用有限元法分析了某核电站排气钢塔的固有振动特性,即一阶、二阶振动频率及振型.在此基础上,研究了结构在地震状态下的不平衡响应,为提高大型结构的防震性能提供依据.
The finite element method is used to analyse the natural vibration of a exhaust chimney with steel structure in a nuclear power plant,such as the first、the second frequency and their model.The non-balanced response during earth-quakes is studied on the basis so that to improve the resisting-earthquake performance on the large structure.
