Example Embodiment

[0032]The following is attachedFigure 1-10To illustrate the preferred embodiments of the present invention, it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033]Figure 1-10As shown, the bending-shear hybrid square steel tube damper of the present invention is mainly composed of a square steel tube, a bending energy dissipation plate, a flange restraining plate, and a connecting bolt. The square steel pipe is made of Q235 steel, low-yield-point steel, etc., and the low-yield seamless steel pipe is preferred; the side of the square steel pipe is a shear energy consumption surface, which can bear the energy consumption of shear load; the welding and bending consumption of both ends of the shear energy consumption surface Energy plate, the bending energy dissipation plate is X-shaped, which can bear the energy consumption of bending load; the upper flange

Abstract

The invention provides a bending and shearing mixed type square steel tube damper. The bending and shearing mixed type square steel tube damper is mainly composed of a square steel tube, bending energy dissipation plates, flange restraining plates and connecting bolts. The side surface of the square steel tube is a rectangular energy dissipation face and can bear shearing load energy dissipation;the bending energy dissipation plates are welded to the two ends of the shearing energy dissipation face, are in an X shape and can bear bending load energy dissipation; and the flange restraining plates are welded to an upper square steel tube flange and a lower square steel tube flange, the flange restraining plates are arranged on the outer sides of the upper square steel tube flange and the lower square steel tube flange and are slightly longer than the upper square steel tube flange and the lower square steel tube flange, bolt holes are reserved in the two ends of the flange restraining plates, and the diameter and the distance of the bolt holes can be determined through calculation according to actual engineering requirements. The square steel tube is connected with frame beams, frame columns and infilled walls through the connecting bolts, and the upper square steel tube flange and the lower square steel tube flange are prevented from yielding and tilting.
