(1 Beijing Urban Engineering Design & Research Institute Co., Ltd., Beijing 100037, China; 2 Beijing Petrochemical Engineering Co., Ltd., Beijing 100107, China)Abstract: 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 interlayer 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 interlayer seismic structure can be a good solution to this contradiction. The differences of the high-level framework structure of interlayer seismic design of old and new seismic code and analysis the influence ofinterlayer seismic impact on the upper and lower structures were compared. It improves that the interlayer seismic isolation frame is economic rational and feasible to the subway car depot platform project.
Keywords: interlayer seisrmc isolation, seismic isolator, time history analysis; horizontal seismic reduction factor; comparison of code
