This paper investigates the seismic performance of posttensioned concrete piers with external viscoelastic dampers to improve the energy dissipation capacity of this type of structure. An installation scheme for viscoelastic dampers on bridge piers is proposed, and the mechanical models of the damper are analyzed according to the installation scheme. By attaching the viscoelastic dampers to the posttensioned bridge piers, the analytical model of the hybrid system is established using the OpenSees finite element analysis package. Cyclic behavior and time history analyses are conducted on a posttensioned bridge with and without viscoelastic dampers using the established finite element model. The analysis results indicate that the viscoelastic dampers can effectively improve the seismic performance of the bridge structures with posttensioned piers.

Based on the mechanics characteristics of the viscoelastic dampers, the seismic performance of a 5 layers steel frame structure with viscoelastic dampers or not was researched. In under the action of the rarely met earthquake, the finite element analysis software MIDAS was used to analyses two of the models of displacements, interlayer shear and ductility of structure. The results showed that: after the installation of viscoelastic dampers, the displacements and interlayer shear of the structure reduced significantly, and ductility increases, the earthquake response can be cut down obviously, it shows better seismic performance.
