Abstract

The target in this study is damage-controlled system with damper installed at beam end. This system should have different design method about strength and stiffness of the damper compared with the general parallel connection damping system(such as braces type or stud type etc.), because both arrangement formats of damper are different. However, the design method of damper installed at beam end is not yet available. And relevant internal and external researches have been limited mostly to the structural performance verification by the shape of the connection detail. Therefore, in this paper, it consider the available design value of damper installed at beam end through the analytical study. The purpose of this study is to present the design range of the damper/beam yield strength ratio and stiffness ratio, presented rationale is based on the performance efficiency of the damper and results of the damage analysis of the beam member. It conducted time history analysis to target the structure made up of the presented design range, to verify the validity of the proposed design value.
