This paper investigates the efficiency of using elastic-gap devices (EGDs) to improve the performance of seismic-isolated bridges (SIBs) in near-fault (NF) zones. The EDG is intended to function at two performance levels under service and maximum considered design level (SDL and MCDL) NF earthquakes to reduce isolator displacements (IDs) while keeping the substructure forces (SFs) at reasonable levels. Analyses of structural models of bridges with EGDs revealed that providing EGD is beneficial for decreasing the IDs to manageable ranges while improving the performance of the isolators by reducing the heat generated.
