摘要
本文在已有研究的基础上,运用SAP2000、ANSYS软件对常规岛主厂房进行弹性分析和罕遇地震作用下的弹塑性变形分析(Pushover分析),分析结构周期、振型和层间位移角特点,绘制能力谱-需求谱曲线,得到了在不同地震作用下核电站常规岛主厂房从弹性阶段到弹塑性阶段的较为完整的结构动力响应。结果表明:多遇地震作用下结构抗震性能良好,结构的周期和振型以及弹性阶段层间位移角满足规范要求;罕遇地震作用下需求谱、能力谱两线相交所得性能点出现较早且处于能力谱的弹性范围内,结构抗震性能满足规范要求。本文分析过程对核电站常规岛主厂房等重大建筑工程的抗震性能分析具有一定的参考和实用价值。
On the basis of existing research,the elastic analysis and elastic-plastic deformation analysis of severe earthquake on the main workshop in conventional island( pushover analysis) is carried out with SAP2000 and ANSYS,including the periods,modes and floor displacement angle among layers of main structure component. By capacity spectrum-demand spectrum curve,the more complete dynamic response of structures from elasticity to elastic-plastic phase is derived. The results show that,under frequent earthquake,the structural seismic performance is good,periods and vibration modes of the structure and the interlayer displacement angle of the elastic stage meet specification requires; under the severe earthquake,the performance point which is got by intersection of the demand spectrum curve and capacity spectrum curve appear early and is in the elastic range of the power spectrum,the structural seismic performance meets the specification requirements. The analysis process for antiseismic performance analysis of main plant building in normal island and other major construction projects has a certain reference price and practical value.
