アルミニウム押出型材を用いたSPDの性能実験と解析的検討

As one of a seismic reinforcement device, Shear Panel Dampers (SPDs) made of steel are used as a seismic damper. Since the aluminum alloy is a lightweight and material superiority against steel, there is worth considering as one of the seismic damper. In this paper, performance tests and analysis of Aluminum Shear Panel Dampers are studied. An aluminum deck of square-hollow sections made of aluminum alloy (A6061S-T6) were used for test specimens. In the tests, monotonic and cyclic loading was applied. As a test result, brittle failure has occurred in shear deformation in less than 6.5%, the Cumulative Inelastic Deformation (CID) was less than 24%. By numerical analysis, it was possible to substantially simulate the test results.
