摘　　要：地铁车辆段上盖住宅可同时满足人们日常居住和出行的要求。文章针对该类结构进行隔震设计。首先,选取大底盘顶部作为隔震层并布置隔震支座,对各类结构构件设定相应的性能目标。其次,分别进行多遇地震、设防地震、罕遇地震下的弹性分析,重点关注隔震支座部位的拉压应力、水平位移、减震系数、抗风和抗倾覆能力等,并对相关构件进行性能化设计。最后,进行罕遇地震下的弹塑性分析,计算楼层位移角、结构构件损伤和隔震支座耗能。结果表明,采用层间隔震是车辆段上盖住宅结构的有效抗震设防手段。文章中提到的设计方法可以对类似的隔震设计提供一定的参考。The residential buildings above the metro depot can simultaneously meet people's daily living and travel requirements.This paper focuses on seismic isolation design for this type of structure.Firstly,select the top of the large chassis as the seismic isolation interface with multiple seismic isolators,and set corresponding performance objectives for various structural components.Secondly,elastic analysis will be conducted under frequent earthquakes,fortification earthquakes,and rare earthquakes,with a focus on the tensile and compressive stress,horizontal displacement,seismic reduction coefficient,wind resistance,and overturning resistance of the seismic isolator.Performance-based design will also be carried out on relevant components.Finally,elastic-plastic analysis will be conducted under rare earthquakes to obtain the story drift ratio,structural component damage,and energy consumption proportion of the seismic isolator.The results indicate that using interlayer seismic isolation is an effective seismic fortification measure for residential buildings above the metro depot.The design methods mentioned in this paper can provide some reference for similar seismic isolation design.
