| Research Abstract |
In the past earthquakes, a lot of timber houses with large stiffness eccentricity were collapsed or heavily damaged owing to torsional vibration. The objective of this research is to propose application of viscoelastic dampers to timber houses. In order to mitigate torsion and seismic damage, stiffness and viscousness should be properly distributed in horizontal direction. Performance evaluation method of shear wall with dampers is also studied through full-scale tests and numerical analyses.
