SEISMIC RETROFIT OF THE BOLU VIADUCT

An evaluation of the seismic isolation design of Bolu Viaduct 1 in Turkey and an assessment of its performance in the 1999 Duzce Earthquake were conducted through nonlinear finite element simulation of near-fault earthquake ground motions. The analysis indicated that the near-fault effects of ground motion at the site induced responses that exceeded the design displacements and capacities of the seismic isolation systems. This resulted in significant damage to the bearings and energy dissipation systems as observed on site. Analysis highlights the distinction between the responses of the viaduct to near-fault and far-field ground motions.
