Description

In case of high-rise buildings, it is important to take measures to avoid vibration caused by wind. One of the measures is setting up the dampers in the buildings. Among them, the viscoelastic damper is effective for vibration caused by wind because it has effects against a small deformation. However, there is concern about changing the performance of it caused by long duration vibration. The purpose of this research is constructing a design method of vibration control buildings considered that the stud-type viscoelastic damper declines performance caused by long duration vibration. We propose the method for assessing the response of vibration control buildings considered that it declines performance by reducing its performance from the initial value.
