屋顶加层对核电站厂房楼层反应谱的影响评估

On influence evaluation of the added floors on the floor response spectrum of workshops in nuclear power stations

以某核电站厂房为分析对象,建立了该厂房屋顶加层变更结构计算模型,对变更后该厂房的楼层反应谱进行了计算,并与参考电站标准设计谱作了比较,评估了该变更对标准设计谱的影响。

It regards one workshop in a nuclear power plant as the analytical object. Establishes the calculation model for the added floors alteration of roofs in the workshops. It calculates floor response spectrum after the design change. The differences between floor response spectrum after the design change and reference are compared. The impact of change on standard design spectrum is evaluated.
