| Abstract |
| This study is aimed at finding its applicability to elasto-plastic damper manufactured by Fe-Mn damping alloy in structure building. Almost existing elasto-plastic damper has been effective for plastic design against the earthquake. On the other hand, elastic design against wind load has been ineffective, because research of suitable material has been imperfect. Accordingly, we make an experiment of increment cyclic loading test with controlling 6-typed displacement to confirm the applicability of Fe-Mn damping alloy to the elasto-plastic damper. In this result of this test, we confirmed the steel plate damper manufactured by Fe-Mn damping alloy showed 3.1 times energy absorption capacity in the skeleton part compared with SS400, 2.0 times capacity in the Bauschinger part and 2.4 times capacity in the total part. Therefore, the steel plate damper with Fe-Mn damping alloy is available for elastic and plastic condition, that is, it can be designed against resisting the earthquake and wind load. |
