【 摘 要 】

Results of original experimental research, obtained during shaking table tests on a large-scale bridge model equipped with an advanced seismic protection system type USI-SF, are presented in the paper. The installed basic seismic isolation system is created by applying novel double spherical rolling seismic bearing (DSRSB) devices, while qualitative upgrading of seismic performances is made using the installed advanced multi-directional space flange energy dissipation (SF-ED) devices. Research results show that significant qualitative improvement of seismic performances of isolated road bridges can be achieved using DSRSB and SF-ED devices.
