| 中文摘要 | 采用根据我国现行《建筑抗震设计规范》生成的人工地震波,对单自由度体系进行弹塑性时程分析,讨论了滞回模型、屈服后刚度等对弹塑性位移反应谱的影响。在此基础上,建立了8度设防、Ⅱ类和Ⅲ类场地、设计地震分组为第一组、位移延性系数μ为1~8的单自由度体系最大弹塑性位移与周期的关系,即常延性系数弹塑性位移谱。通过算例,介绍了常延性系数弹塑性位移谱在房屋结构基于位移抗震设计中的应用。; Artificial earthquake ground motions are generated according to the response spectrum specified in the Code for Seismic Design of Buildings. By nonlinear time history analysis of SDOF systems, influence of hysteretic model and post-yield stiffness on the inelastic displacement spectrum is discussed. Relationship between the maximum inelastic displacement and period for SDOF systems with displacement ductility ratio of 1~8, i.e., the constant ductility inelastic displacement spectra, are established for seismic fortification intensity 8, site soil classification Ⅱ and Ⅲ, and design seismic group 1. Application of the constant ductility inelastic displacement spectrum to the displacement-based seismic design of building structures is introduced by a sample calculation.; 北京市教委与北京市自然科学基金联合重点资助项目(kz200410005003) |
