DYNAMIC BEHAVIOR OF STEEL FRAME INSTALLING STUD COLUMN WITH VISCOELASTIC DAMPER

Abstract

Dynamic loading tests on one bay-three story steel frames installing a stud column with a viscoelastic damper are conducted to investigate the dynamic behavior of the frames and the effect of response control by the damper. A total of six frames are tested with different damper arrangement and loading speeds. Differences of the stiffness, damping properties and story drifts between stories with and without the damper are discussed. It is found that the rotation at the center of beam where the damper attaches significantly affects the behavior of the whole frame and the damper.
