Abstract

The invention relates to the field of general building structures, in particular to a self-adaptive variable frequency tuned mass damping device and a self-adaptive frequency variation method for controlling the vibration of a high rise or tall building. The self-adaptive variable frequency tuned mass damping device overcomes the defects that the prior tuned mass damper cannot well control the vibrations of a plurality of frequencies of a controlled structure, has a simple structure and needs the support from external energy. The self-adaptive variable frequency tuned mass damping device comprises a tuned mass damper which comprises a mass block, a damper and an elastic component, wherein the self-adaptive variable frequency tuned mass damping device also comprises a small spring mass system with a specific natural frequency; and the small spring mass system consists of the elastic component and a small mass block and is connected with the tuned mass damper through variable rigidness driving systems which are connected in a parallel mode or in a series mode. The self-adaptive variable frequency tuned mass damping device achieves the aim of better controlling the vibrations of a controlled structure at a plurality of frequencies and has the advantages of simple structure, convenient manufacture, no need of external energy in work, and low cost.

Description

technical field [0001] The invention relates to the field of general building construction, in particular to an adaptive frequency conversion tuning mass damping vibration reduction device and an adaptive frequency conversion method for controlling the vibration of high-rise or towering buildings. Background technique [0002] In recent years, with the advancement of technology, a large number of high-strength and lightweight building materials have been used in buildings, and as their heights have become higher and higher, the structural damping of buildings has continued to decrease. Under dynamic loads such as strong winds and earthquakes, high-rise Or high-rise buildings will produce relatively strong vibrations, which will not only make users feel uncomfortable and cause panic, but also cause excessive vibrations to cause failure and destruction of building structures. For this reason, people have proposed mechanism vibration control methods. Structural vibration contro...
