Outline of Final Research Achievements |
This research was conducted to evaluate the seismic performance of a new developed response control mechanism which aims to standardization of response control system for wooden houses. The response control mechanism consists of two cylindrical dampers and a slippage connection. The damper is filled with high damping rubber which is subjected to shear force. Where shear strain of the high damping rubber reaches to about 100%, slippage of the connection occurs to realize high ductility. As a result, it was confirmed that the mechanism has 13.7 kN of allowable shear strength considering some kinds of dependency and manufacturing variation. Furthermore, it was found that response story displacement of a wooden house with the system reduces to under 50% due to earthquake response analysis.
