Problems solved by technology

However, on the one hand, this technology takes up a lot of space, has a complex structure, and high engineering cost. On the other hand, once the structure of the suspended mass block fails, the falling mass block will damage the structure and cause potential safety hazards.
[0004] The traditional tuned mass damper is heavy, and installing it on the structure will not only increase the vertical load of the structure, but may even increase the dynamic response of the structure, and it is inconvenient to adjust the tuning frequency of the damping device, making installation difficult and costly

Abstract

The invention discloses a performance-recoverable mass tuning damping structure without an additional mass block. The structure comprises an upper reinforced concrete floor system, reinforced concretecolumns and a lower reinforced concrete floor system, the top end of each reinforced concrete column is fixedly connected with the upper reinforced concrete floor system while the bottom end of the same is fixedly connected with the lower reinforced concrete floor system; a damping unit is fixedly arranged at each of the top and the bottom of reinforced concrete, each damping unit comprises a steel plate barrel fixedly socketed on the reinforced concrete and a plurality of soft steel dampers arranged around the circumferential direction of the steel plate barrel, one end of a soft steel platevertically arranged in each soft steel damper is connected with the corresponding steel plate barrel while the other end of the same is connected with a T-shaped connection plate, and the other end of each T-shaped connection plate is connected with an anchoring beam in the upper reinforced concrete floor system or an anchoring beam in the lower reinforced concrete floor system. The structure issimple in structure, low in cost, good in damping effect and capable of quickly recovering performance.

Description

technical field [0001] The invention relates to the technical field of shock-absorbing structures, in particular to a performance-recoverable mass-tuned shock-absorbing structure without an additional mass block. Background technique [0002] In recent years, mass-tuned damper (TMD) has been widely used as an energy-dissipating shock-absorbing device, and its good working performance has also been verified by a large number of projects. The tuned mass damper is composed of a mass block, a spring and a damping system, that is, through the spring and the mass block, its vibration frequency is adjusted to the vicinity of the structural frequency, thereby changing the resonance characteristics of the building structure, and using the damping system to dissipate the input seismic energy to To achieve the effect of shock absorption. [0003] In the current field of engineering structures, there are mainly two types of slide rail-type tuned mass dampers and suspended-type tuned ma...
