Description

technical field [0001] The invention is a tuning vibration damping device for building structures, which is used for dynamic effect control caused by earthquake action or wind load, belongs to the technical field of energy consumption vibration damping control of building structures, and specifically relates to an integrated tuning mass damping wall . Background technique [0002] With the improvement of anti-vibration (seismic) requirements for civil engineering structures, more and more engineering structures adopt structural vibration control technology. At present, the passive control technology is more commonly used, which mainly includes two categories: energy dissipation and vibration reduction technology and tuning vibration reduction technology. [0003] Tuned Mass Damper (TMD) is a very effective tuned vibration damping device, which can effectively attenuate the response of structures under dynamic loads such as earthquakes and wind loads, and has been widely use...

AI Technical Summary

Problems solved by technology

Some tuned mass dampers that have been disclosed usually need to concentrate and attach huge mass blocks in the structure, which not only occupies a certain building space, but also causes a large load-bearing burden on the floor; at the same time, because of the limitation of the floor position and mass , the vibration control frequency range is narrow, and the vibration reduction effect on broadband dynamic loads such as earthquake action is small; various devices with partial tuning mass damping are exposed in the working environment, and their performance is easily affected by the environment

[0004] In recent years, due to the advantages of making full use of the space provided by the wall and strong energy dissipation capacity, damping walls have increasingly appeared in the vibration control design of building structures. However, most of the currently disclosed damping walls (such as sticky Hysteretic damping wall (application number 201410262093.5), viscoelastic damping wall (application number 201310124804.8), lead damping wall (application number 201110130891.6), magnetorheological intelligent damping wall (patent number ZL200420037740.4), etc.) are all based on energy dissipation and vibration reduction The principle of the device, the damping wall using the principle of tuned vibration reduction is rarely reported

At the same time, this type of device based on the principle of energy dissipation and vibration reduction often requires a certain deformation of the main structure (such as structural deformation under the action of a large earthquake) in order to provide better damping and energy dissipation capabilities, which limits the performance of the damping wall to a certain extent. application
