Problems solved by technology

The most obvious is that the general tuning system only conducts independent vibration reduction design for the vibration of the structure in a certain direction, and the effect of multi-dimensional vibration control, especially vertical and torsional vibration control is not good.
In addition, the cost of traditional TMD and TLD is relatively high, and the installation is limited, which is not conducive to wide application

Embodiment 1

[0036] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] A towering structure is located in the eight-degree seismic fortification zone, and it is necessary to consider the application of shock-absorbing measures to improve the seismic-resistance capacity. The building has a plane size of 18m×12m, a height of 60m, and a basic period of 1.89s. According to actual needs, the composite omnidirectional tuning shock-absorbing damping pendulum is arranged.

[0038] Such as Figure 1 to Figure 7As shown, it is an embodiment of a composite omnidirectional tuning shock-absorbing damping pendulum of the present invention, which mainly includes the upper steel plate 1 of the vibration-isolation spring, the vibration-isolation spring 2, the lower steel plate 3 of the vibration-isolation spring, the rigid suspender 4, and the damper Box body 5, mass block 6, damping particles 7, vertical steel partition...

Abstract

The invention provides a compound type omni-directional tuning and shock-absorption damping pendulum and belongs to the technical field of shock resistance and absorption of structural engineering. The compound type omni-directional tuning and shock-absorption damping pendulum comprises a shock insulation spring upper portion steel plate, a shock insulation spring, a shock insulation spring lower portion steel plate, a rigid hanging rod, a damping pendulum box body, a mass block, damping particles, a vertical steel partition plate, a damping hole, a damping hole plate, a transverse steel partition plate, a pendulum hinge and tuning liquid. All of members and the mass block inside the damping pendulum box body serve as horizontal direction turning mass to perform shock absorption and energy dissipation. All of member under a vertical shock-absorption spring serve as vertical direction, swing direction and reversing direction turning mass to perform shock absorption and energy dissipation, and accordingly shock absorption and energy dissipation functions of the damping pendulum in all directions are finally achieved. The damping pendulum has the advantages of having a multi-dimensional shock-absorption function, simple in manufacture, flexible and convenient to arrange and the like.

Description

technical field [0001] The invention relates to a damping pendulum capable of tuning energy consumption and shock absorption in all directions of the structure (horizontal directions, vertical directions, torsion and swing directions), and belongs to the technical field of shock resistance and shock absorption of structural engineering. Background technique [0002] The ground motion during an earthquake is a complex multi-dimensional motion, and the period and phase of each point are different, resulting in the motion of each particle on the ground not only having a translational component but also a rotational component (a torsional component that rotates around a vertical axis and two components that revolve around a vertical axis). The swing component of horizontal axis rotation), the multi-dimensional characteristics of ground motion determine that the dynamic characteristics of building structures under earthquakes are also multi-dimensional, including both horizontal a...
