摘要

2010版《建筑抗震设计规范》明确提出隔震层可以设置在上部与下部结构之间,使层间隔震技术得以广泛推广应用。无锡地铁车辆段大平台上盖开发项目,受地铁车辆限制,平台层高大,造成平台与上部结构层刚度比问题突出,利用层间隔震结构可以很好地解决这一矛盾。比较了高层框架结构层间隔震设计新旧抗震规范的不同,分析了层间隔震对上下部结构的影响,证明层间隔震结构在车辆段大平台开发项目中是经济合理可行的。
The 2010 edition of Code for seismic design of buildings explicitly pointed out that the isolation layer can be set between the upper and lower structures and it extends the interiayer seismic technology.The development of Wuxi subway car depot platform on the cover project was limited by the subway car,and the platform is too high,that led serious problems to the platform and the upper structure layer stiffness ratio.The interiayer seismic structure can be a good solution to this contradiction.The differences of the high-level framework structure of interiayer seismic design of old and new seismic code and analysis the influence of interiayer seismic impact on the upper and lower structures were compared.It improves that the interiayer seismic isolation frame is economic rational and feasible to the subway car depot platform project.
