Abstract
A method for enhancing the seismic performance of isolated bridges was developed using innovative vertical multigap (V-MG) devices based on extensive experimental and analytical research. Significant improvements in seismic performance were achieved by creating a unique type of uniform V-MG energy-dissipation device for a vertical-gaped bridge protection system (VG bridge system) that included double spherical rolling seismic bearings for seismic isolation as a complete set. Seismic shaking table tests on large-scale bridge models, which simulated real earthquake conditions, confirmed that the VG bridge system could significantly modify seismic response and enhance the seismic safety of isolated bridges under very strong earthquakes.
