Problems solved by technology

However, due to the synergistic effects of tension, shear, and torsion, the stress state is complex, and it is prone to instability.
[0003] In the prior art, there is no reliable solution to the buckling instability of the U-shaped metal damper, and the joints of the U-shaped mild steel plate in the damper are prone to obvious stress concentratio...

Embodiment

[0028] see figure 1 , image 3 , Figure 4 As shown, the present invention is a U-shaped mild steel damper with a limit sleeve. The main body of the damper is composed of a rectangular protective shell 2, a sliding guide rod 1, a rectangular guide rod 4, a spring 9, and a U-shaped mild steel plate core member 5. . The rectangular guide rod 4 and the U-shaped mild steel plate 5 have the same width and are in the same plane; the output of the damper can be adjusted by changing the width or the thickness of the U-shaped mild steel plate 5 . The first row and the second row of U-shaped soft steel plates 5 are respectively fixed on the rectangular guide rod 4 and the protective shell 2 by fixing parts 3 and 6, and the ends of each U-shaped soft steel plate 5 are welded on the protective shell 2 and the rectangular guide rod 4 superior.

[0029] The protective shell 2 is used to limit the displacement of the rectangular guide rod 4 in the out-of-plane direction, so as to prevent...

Abstract

The invention discloses a limit sleeve U-shaped soft steel energy dissipation damper. A protective shell is added in the limit sleeve U-shaped soft steel energy dissipation damper to prevent a U-shaped soft steel damper from buckling instability out of the surface; a fixing piece for fixing U-shaped soft steel plate is added in the limit sleeve U-shaped soft steel energy dissipation damper, the cross section is designed as a special arc shape, the arc fixing piece can prevent a serious stress concentration phenomenon generated in the position of fixing the U-shaped soft steel plate; a main body of the U-shaped soft steel damper is composed of the U-shaped soft steel plate, springs, sliding guide rods, rectangular guide rods and the protective shell; and two ends of the sliding guide rods are provided with ultimate displacement protection plates to avoid oversize deformation to suddenly break a damper. The limit sleeve U-shaped soft steel energy dissipation damper is simple in structure, low in price and easy to produce in batches, and can be applied to energy dissipation vibration reduction systems with various structures.

Description

technical field [0001] The invention relates to an energy-dissipating shock-absorbing device for a building structure, in particular to a U-shaped mild steel damper with a limit sleeve. Background technique [0002] With the development of the anti-seismic and wind-resistant design theory of civil engineering structures, the idea of ​​energy dissipation and shock absorption has been applied in various types of anti-seismic construction projects, and the design and use of energy dissipation components and energy dissipation dampers have become more and more common. Among them, the metal yield damper can provide additional stiffness and damping for the structure at the same time, has stable hysteretic characteristics, good low-cycle fatigue resistance, and strong adaptability to the environment, making it have a very wide application prospect in practical engineering. Metallic yield dampers with superior performance are ideal for controlling the displacement response of struct...
