【摘要】：为研究核电站结构-设备相互作用的地震反应,针对某高温气冷堆核电站反应堆进行结构与设备相互作用的地震反应分析研究,通过对考虑与不考虑结构-设备相互作用的模型进行对比,开展模态分析、设计基准地震动下和超设计基准地震动下的动力特性分析以及楼层反应谱分析,结果表明:考虑剪力墙主体结构与设备的相互作用后,结构的地震反应减小,层间剪力最大减小60%,水平向楼层反应谱峰值减小为不考虑相互作用时的40%,提高了结构与设备的安全性,并为设备抗震设计提供依据。但竖向楼层反应谱在结构竖向周期附近有放大作用,建议在设备抗震设计时予以注意。
[Abstract]:In order to study the seismic response of structural equipment interaction in nuclear power plant, the seismic response analysis of the interaction between structure and equipment in a nuclear power plant reactor of a high temperature gas cooled reactor is studied. By comparing the model considering the interaction between the structure and equipment, the modal analysis is carried out, and the base ground motion and the super design datum are designed. The dynamic characteristic analysis and the floor response spectrum analysis show that, after considering the interaction between the main structure and the equipment, the seismic response of the structure is reduced, the maximum interlayer shear force decreases by 60%, the peak of the horizontal floor response spectrum decreases to 40% when the interaction is not considered, and the safety of the structure and equipment is improved. It provides a basis for seismic design of the equipment. However, the vertical floor response spectrum has amplification effect near the vertical period of the structure, so it is recommended to pay attention to the aseismic design of the equipment.
