【摘要】 为了对核电常规岛主厂房结构抗震进行分析,通过工程实例分析基于性能的抗震设计的优点,并在不同的抗震性能目标控制下,运用SAP2000有限元程序,对主厂房结构进行静力弹塑性分析,绘制能力谱-需求谱曲线,分析结构主要构件应力、应变和楼层层间位移角特点,检验结构的抗震性能。结果表明:主厂房结构应力、应变合理,层间位移角满足规范要求。该成果对基于性能的抗震设计方法的运用和推广具有一定的参考价值。更多还原

【Abstract】 The paper take the seismic analysis of main power plant of the nuclear power conventional island as an engineering example to analysis the advantage of the design of performance-based seismic analysis.And The seismic analysis for main power plant structure is made with finite element program of SAP2000,using Pushover method,under control of different seismic performance goals.The authors also protract capacity spectrum-demand spectrum curve,analysis the characteristic of stress,strain and floor displacement angle among layers of main structure component,in order to test the seismic performance of structure.The results show that,the stress and strain of main power plant structure are reasonable,and the floor displacement angle among layers satisfy the standard requirement.This regularity so obtained can provide a certain reference value and guiding significance for the method of the design of performance-based seismic analysis.更多还原
