AP1000核电机组屏蔽厂房层间隔震结构及其抗震性能研究

Shield Building with Inter-Story Isolation for AP1000 Nuclear Power Units and Its Seismic Performance Study

针对AP1000核电机组屏蔽厂房的结构特点,建立了结构参数优化模型,通过修改屏蔽厂房各部分之间的连接方式,构建了该屏蔽厂房的层间隔震新型结构。与传统屏蔽厂房结构、基础隔震结构等模型比较,表明了本新型结构的减震机理不同,并验证了本新型结构具有显著的减震效果、稳定的抗震鲁棒性和良好的场地适用性。

Based on the features of the shield building for AP1000 nuclear power units,the optimal model of the shield building for stiffness and damper is given,and the new structural system with inter-story isolation is established by modifying the connection between different parts of the shield building.By comparing with the seismic responses of the traditional model and the base isolation model,the different vibration mechanism of the inter-story isolation model is shown obviously,and its earthquake resistant behaviors (i.e.,reduction effect stability,anti-seismic robust, and adaptive site)are presented.
