Embodiment 1

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 2 As shown, it is an embodiment of a built-in particle type tuning and frictional collision energy dissipation damper of the present invention, which mainly includes a box body 1, a damping particle group 2 placed in the box body, a partition inside the box body 3, and a connecting member 4 The original beam member 5 of the structure connected with the box body 1.

[0026] The box body 1 is poured with high-strength concrete, and the connection member 4 formed by high-strength bolts is riveted with one side of the original beam member 5 . The box body 1 is generally arranged symmetrically on both sides of the original beam member 5 of the structure. The internal partition 3 of the box is a flat steel plate with a thickness of 6mm, which divides the box 1 evenly into two parts along the beam height direction, such as ...

Abstract

The invention relates to a built-in micro-particle type tuning and friction energy dissipation damper, belonging to the field of structural engineering earthquake proofing and damping and wind resistance technology, and comprising that: a box body connected with a building structure floor member or a beam column member, damping particles placed in the box body, an internal clapboard and a connecting member of the box body; the damping particles are evenly stacked in a space formed by the box body, the internal clapboard and the connecting member in appropriate volume according to actual conditions; under the action of wind or earthquake, the whole box body can tune the natural vibration characteristic of the structure, and multidimensional vibration, friction and collision can fully occur between each damping particle as well as between the damping particles and the internal clapboard. The built-in micro-particle type tuning and friction energy dissipation damper of the invention has simple construction, convenient installation and adjustment, agile reaction and functions of multidimensional tuning damping and friction and collision damping, and can effectively reduce the reaction of the original structure under the dynamic action of wind or / and earthquake and the destructiveness of the original structure.

Description

technical field [0001] The invention relates to a damper with damping particles placed inside and has the functions of tuning and frictional collision energy consumption, and belongs to the technical field of anti-seismic, shock-absorbing and wind-resistant structural engineering. Background technique [0002] In recent years, the tuned mass or tuned liquid vibration damping control technology has been developed rapidly because it does not need to take traditional strengthening measures for the structure, and the damping effect is obvious and easy to implement. The tuning system is to add inertial mass on the top layer of the structure or add flowing liquid inside the auxiliary structure, and connect the structure with springs and dampers to control certain vibration modes of the structure. The basic principle of tuned mass or tuned liquid damper is to use the secondary system to absorb the vibration energy of the host structure so that the vibration response of the host str...
