A STUDY ON HYSTERETIC PERFORMANCE OF THE STUD-TYPE PANEL DAMPER WITH STEEL SUPPORT UNDER COMPRESSIVE AXIAL FORCE

Abstract

Under stud-type shear panel damper using low-yield strength steel is installed in mid- and high-rise buildings, there is a problem derived from the excessive axial force by the variable axial force. In this paper, the effect of compressive axial force on the hysteresis characteristic of the damper is examined by experiment and FEM analysis. In consequence, the stable hysteresis was provided under compressive axial force ratio less than 0.3 with specific combination of flange and shear panel. Also, the influence of the hysteretic performance of the stud-type panel damper subjected to bi-directional horizontal loading and axial force is minor.
