大亚湾核电站继电器机架改造支撑动力时程分析
|
摘要
为更准确地得到结构在地震作用时的应力响应,本文对大亚湾核电站继电器机架改造支撑结构在水平和垂向地震载荷共同作用下进行动力时程分析,计入继电器机架上、下支撑点处相对位移的影响,并按最不利组合施加于计算模型,得到输出与输入的传递函数,验证计算结果的真实性,为核电厂继电器机架结构支撑改造提供参考。
For obtaining the stress response accurately of the Relay Frame's Reconstructed Support of Daya Bay Nuclear Power Plant(NNP) under the horizontal and vertical seismic load,dynamic time-history method is used.The method considers the relative displacement between the top support and the bottom sup-port,which is applied by the worst-case combination.From the analysis results,the output and input transfer function is obtained,which can verify the analysis results and supply as a reference for the improvement of the relay frame support.
