INFLUENCE OF HYSTERESIS CHARACTERISTICS OF DAMERS AND DEFORMATION-CONTROL DEVICES ON STORY DRIFT ANGLE AND FLOOR ACCELERATION OF STEEL BUILDINGS AT DIFFERENT EARTHQUAKE GROUND MOTION LEVELS

Abstract

Recently, as a measure against huge earthquake motion, the design methods using the dampers and deformation-control devices are supposed. This design methods would suppress the story drift angles for huge earthquake motion, but could increase the floor acceleration for small or medium earthquake motion. Therefore, in this paper, the hysteresis characteristics of the dampers and the deformation-control devices on story drift angle and floor acceleration at different earthquake ground motion levels are investigated by time history response analysis.
