【 摘 要 】

A nonlinear 3D analytical model, experimentally validated by seismic shaking table tests of a large-scale bridge model constructed with upgraded seismically isolated system with space flange devices, representing an advanced USI-SF seismic protection system, is presented. Seismic protection advances of USI-SF system are demonstrated through comparative analysis of the model prototype with the proposed new system. Technological options for qualitative upgrading of various types of isolated bridges are made possible with structural generalization of SF-ED devices.
