Abstract: For two large span footbridges, which supported by rubber bearings in both ends, we analysis and check the defections and vibration in the design first. And then run elastic time history analysis in seisnuc level l, and run elastic-plastic nonlinear time history analysis in seismic level 3,to estimate the performance of rubber bearings and footMdges. Finally, make sure the smallest width of seismic meets between the footbridge and towers.
Keywords: footMdge; rubber bearing; seismic isolation
