Simple response evaluation method of steel frames with stud-type damper composed by visco-elastic material and two steel columns.

Abstract

This paper presents a simple response evaluation method of steel frames with stud-type damper composed by visco-elastic material and two steel columns. In order to obtain earthquake response of the system correctly, a detailed analysis model may be preferred. However, this analysis requires so much amount of time that simple response evaluation method is proposed. The method is based on the damping factor and the damper deformations. The validity of the proposed method is verified by comparing with earthquake response analysis result of the detailed model.
