Seismic effects on a planned highway bridge in active seismic zone near Žilina (Slovakia) were analysed. Seismic analysis has proved that due to strong earthquake an inelastic structural response is likely. Due to great seismic design forces, increase of foundation dimensions was necessary. An alternative solution has been proposed using seismic isolators and dampers that reduce the seismic design forces in piers. As a result, the change of the dimensions was not necessary. These two alternatives and
estimated costs were compared. and Obsahuje seznam literatury
