摘要：

以建筑抗震设计规范标准为依据，采用有限元法对某核电低压缸及凝汽器结构的地震响应进行了分析，通过地震时程分析法和反应谱分析法得到低压缸及凝汽器在水平和竖向方向地震荷载作用下的位移响应特征．结果表明，该低压缸及凝汽器结构的地震响应呈现出板结构的振型特征，其抗震性能优于一般的建筑结构．

关键词: 低压缸及凝汽器, 地震响应, 时程分析, 反应谱分析

Abstract:

A series of finite element method (FEM) analysis were carried out to study the seismic response of the nuclear low pressure cylinder and condenser, based on the code for seismic design of building. Seismic response characteristics of the nuclear low pressure cylinder and condenser were obtained through the seismic time history analysis and spectrum analysis. The results show that the seismic response of the nuclear low pressure cylinder and condenser presents some vibration model features of plate structures, and has a better aseismic performance than general building.

Key words: low pressure cylinder and condenser, seismic response, time history analysis, response spectrum analysis
