5MW低功率堆堆厂房结构抗震校核

Aseismic Check of Building structure for 5MW Low Power Reactor

用等效静力分析对5MW 低功率堆堆厂房结构作了抗震校核。根据 IAEA-TECDOC-348的规定计算出各楼层的水平剪力:按我国有关规范进行载荷组合,对重要节点做了强度校核。最后对堆厂房的抗震安全性能作出了评价。结果表明,厂房的关键部位在7度地震下是安全的。

In this paper the aseismic check of building structure ismade by using equivalent static analysis for 5MW Low PowerReactor.According to IAEA-TECDOC-348,horizontal shear ondifferent floors(or nodes)of building is calculated.In accord-ance with the Chines relevant codes,the loads are combined andthe strenth check are given at key nodes.At last the aseismicsafety characteristics of building structure is evaluated.It isshowed that the key sections of the building are safety whenthe earthquake(I_(max)=7)occures.
