Abstract

Viscous damper is a kind of velocity-related damper without rigidity. It can dissipative seismic energy and also can effectively reduce vibration of the structure .In this paper, a dynamic experiment for L-shaped eccentric structure was carried out to compare and verify seismic energy dissipation effect under seismic excitation with viscous damper. A 4-layer L-shaped eccentric structure with and without viscous damper under seismic excitation has been analyzed by Finite element method, and through the model test to validate it. From the comparative analysis, under seismic excitation the torsion of the eccentric structure is significant. Compared with no damper eccentric structure, the dissipation performance of the eccentric structure with damper is more obvious. Different arrangement of the dampers affect the eccentric structural damping effect. For L-shaped eccentric structure with damper, Should find the best arrangement location of damper to confirm optimal control. Through this study, provide a theoretical basis and reference for the eccentric structure in practical engineering.
