Study on Torsional Response of Timber Houses and Torsional Response Control by Supplemental Stiffness and Damping

在过去的地震中，许多刚度偏心率较大的木结构房屋由于扭振而倒塌或严重破坏。本研究的目的是提出粘弹性阻尼器在木结构房屋中的应用。为了减轻扭转和地震破坏，刚度和粘性应在水平方向上合理分布。通过全尺寸试验和数值分析，研究了带阻尼器剪力墙的性能评价方法。

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.
