Energy Consumption Performance Study of New Box-Shaped Hysteretic Damper

Abstract:

To the H-shaped Mild steel damper which has been applied to the market, this paper proposes the opening box dampers were made in material Q235 steel. Studied the influence of the angular size between Webs and vertical direction to the box-shaped Mild steel damper by FEM ABAQUS. The results indicated that under the same rate in the web openings, box dampers has the same yield displacement and hysteresis curves were fuller than H-shaped dampers. With the increase of web and vertical angles, the initial stiffness of the damper box steel and yield strength and yield stiffness of the damper would reduced, but all of these are larger than H-shaped steel dampers; Meanwhile, moment of inertia of box dampers’ two webs to Y-axis is larger , which greatly enhancing the stability of the outside plane to the damper, the larger Web angles, the stronger yield strength and the stability of the outside plane.
