Problems solved by technology

The damper is an excellent energy-dissipating and shock-absorbing device, but the current damper usually only participates in one type of shock-absorbing energy-dissipating, and cannot fully realize the sufficient shock-absorbing and energy-dissipating structure under complex multi-dimensional earthquake motions.

Embodiment 1

[0028] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] The proposed composite low-yield point metal damper with multi-dimensional energy dissipation function can play the role of energy dissipation and shock absorption in any direction in the plane, and it is also a damper with vibration damping and reset functions in the vertical and torsional directions . It includes a bending energy dissipation damper (1), a shearing energy dissipation damper (2), an inner steel cylinder (3), an outer steel cylinder (4), an outer steel ring (5) and a steel plate (6).

[0030] The implementation steps are as follows:

[0031] 1) In this example, the applied building is a steel-concrete frame structure with a total of 5 floors and a floor height of 4.2m. For the part of the frame where the damper is installed, the upper end of the damper is fixedly connected to the beam-column node, and the lower end is ...

Abstract

The invention discloses a composite low-yield-point metal damper with a multi-dimensional energy dissipation function. The composite low-yield-point metal damper is arranged in an interlayer support, aims to play a role in energy dissipation and shock absorption in any direction in a plane, and simultaneously has vibration damping and resetting functions in the vertical direction and the torsion direction. The damper consists of a bending energy-dissipation damper, a shearing energy-dissipation damper, an inner steel cylinder, an outer steel cylinder, an outer steel ring and a steel plate, and is characterized in that the inner steel cylinder, the outer steel cylinder and the outer steel ring are coaxial, the bending energy-dissipation damper and the shearing energy-dissipation damper are horizontally and symmetrically arranged along the radial direction of the circumference of the steel cylinder, two ends of the bending energy-dissipation damper and the shearing energy-dissipation damper are respectively fixed on the inner steel cylinder and the outer steel cylinder, one side of the outer steel cylinder is welded, one side of the inner steel cylinder is welded, the outer steel cylinder and the outer steel ring are coaxial, the steel plates are horizontally and symmetrically arranged in the radial direction of the circumference and fixed in a welding mode, and the two ends of each steel plate are fixed to the outer steel cylinder and the outer steel ring respectively. According to the composite low-yield-point metal damper, deformation, energy dissipation and shock absorption can be carried out in any direction in a plane, in the vertical direction and in the torsion direction, the yield strength is low, and the energy dissipation efficiency is high.

Description

technical field [0001] The invention relates to a composite low-yield-point metal damper with multi-dimensional energy consumption function, which can be deformed, energy-dissipated and shock-absorbed in any direction in the plane, vertically and torsionally, and has low yield strength and high energy-dissipation efficiency. The invention belongs to the technical field of disaster prevention and mitigation in civil engineering. Background technique [0002] Most areas in my country need to consider earthquake-resistant fortifications, and it is of great significance to improve the level of earthquake-resistant and shock-absorbing technology for building structures. The damper is an excellent energy-dissipating shock-absorbing device, but the current damper usually only participates in one type of shock-absorbing energy-dissipating, and cannot fully realize the sufficient shock-absorbing and energy-dissipating structure under complex multi-dimensional earthquake motions. The...
