• Abstract:
  In this review of seismic bearings, a compendium of public domain resources provides off-the-shelf, state-of-the-art bearing types, manufacturers, researchers, and load-deformation response data. Performance of two select seismic bearings, one generally available and one proprietary, is then assessed using finite element modeling and simulation. The influence of seismic bearing effective stiffness is evaluated in terms of reduction of peak in-plane bending moments computed in critical elements of select multi-column pier and trestle substructures used in highway bridges in north Mississippi for a simulated scenario earthquake event.
