Abstract
AbstractThe conventional vertical circulation stereo garage is susceptible to deformation and instability when subjected to extreme seismic loads and complex working conditions. The present study introduces the combination arrangement of steel pipe and friction damper to optimize vertical circulation stereo garage while also investigating their seismic suppression performance under three representative seismic waves (EL‐CNENTRO, TH1TG025(TH), and RH1TG025(RH)). The results showed that the garage structure hasbetter seismic suppression performance when the combination of steel pipes and friction dampers is applied in Scheme 4 compared to relying solely on diagonal tie rod, steel pipe or friction damper. And Scheme 4 achieves inhibition rates of up to 61.27%, 22.12%, 56.07%, and 12.84% for overall maximum deformation response, maximum Y‐direction deformation response, vertex acceleration response, and bottom shear response, respectively. This enhancement significantly improves the garage's seismic stability, providing valuable theoretical references for advancing the development and market promotion of vertical circulation stereo garages.
