Abstract:Three types of metallic yielding energy dissipation devices, named as round-hole metallic damper, double X-shaped metallic damper and metallic yielding-friction damper are presented. Quasi-static tests with scale models of the metallic dampers specimens were carried out, respectively. The test results clearly reveal that these dampers not only have certain stiffness and but also good capacity of energy dissipating. The simplified design procedure for the structure with these energy dissipation devices was summarized. Above three types of metallic dampers were designed based on the procedure and applied in actual structures to improve initial stiffness of original structural under normal use or frequency earthquake and to dissipate inputting energy during great earthquake. In addition, numerical models were established using finite element software and dynamic response comparison of the structures with and without these metallic yielding energy dissipation devices were conducted.
