Embodiment Construction

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

[0033] Figure 1-10 As shown, the bending-shear hybrid square steel pipe damper of the present invention is mainly composed of square steel pipes, bending energy dissipation plates, flange restraint plates, and connecting bolts. Among them, the square steel pipe is made of Q235 steel, low yield point steel, etc., and the low yield point seamless steel pipe is preferred; the side of the square steel pipe is the shear energy dissipation surface, which can bear the shear load energy consumption; the welding bending loss at both ends of the shear energy dissipation surface Energy plate, the bending energy dissipation plate is X-shaped, which can bear the bending load and energy dissi...

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.

Description

technical field [0001] The invention relates to a square steel pipe bending-shear hybrid damper and a method thereof, belonging to the technical field of shock absorption of engineering structures. Background technique [0002] Earthquake, as one of the natural disasters, poses a great threat to the survival and development of human beings, and the direct and indirect losses caused are difficult to estimate. Metal dampers are generally installed in non-load-bearing structural parts, and the main structure is preserved through the deformation and energy dissipation of the dampers, which not only enhances the shock absorption performance of the house, but also realizes the function of recoverable functions after the earthquake. Traditional metal dampers have complex structures and high costs, and are mainly used in high-rise or super high-rise buildings, and are not suitable for low-rise buildings. [0003] The invention proposes a bending-shear hybrid square steel pipe metal...
