摘　　要：为了有效地提高主厂房的抗震能力,增强其安全性,在通用有限元软件SAP2000中建立了相应的线弹性结构模型,用以大型火力发电厂研究结构的动力特性,包括振型、薄弱层分布、质量分布、刚度分布;从体系层面上考察了结构形式的抗震性能是否合理,以及有无可优化的可能,同时为主厂房的大震设计和工程应用提供强有力的依据。In order to improve the seismic resistance capacity of main workshop of large thermal power plant effec- tively and increase its security, based on the general finite element software SAP2000 this paper establishes the cor- responding linear elastic structure model to study the dynamic characteristics of structure, including the mode, dis- tribution of the stiffness, mass and weak layer. From sight of system, it is explored whether or not the seismic behav- ior is reasonable and there is probability of optimization to provide a strong basis for the strong earthquake design and engineering application the of main workshop.
