非線形型粘弾性ダンパーを有する間柱型制振構造の多質点系モデル置換による簡易評価法の適用限界に関する研究

It is aimed at finding the application limit with respect to the simple evaluation method of a stud type vibration control structure with the nonlinear viscoelastic damper. We examined the application limit by using the input level of the earthquake motion as parameters. It was confirmed that the accuracy of this evaluation method is lowered in the boundary between the damper installation story and the non-installation story. This tendency becomes prominent as the input level of the earthquake motion increases and the ductility factor increases. This method can be evaluated very accurately as long as plasticization does not occur.
