SIMPLE EVALUATION BY MULTI DEGREE OF FREEDOM SYSTEM MODEL OF STUD TYPE VIBRATION CONTROL STRUCTURE WITH NONLINEAR VISCOELASTIC DAMPER

Abstract

The simple evaluation method of stud type vibration control structure with nonlinear viscoelastic damper was shown. In this method, loss displacement of stud type damper can be appropriately considered by replacing the damper with an elasto-plastic spring and performing pushover analysis. By reflecting the loss displacement in the multi degree of freedom system model, simple and accurate dynamic analysis is made possible. The accuracy of this method was proved by a case study in a real building.
