Problems solved by technology

However, the surface pressure of the traditional friction damper is very high, and the material of the friction pair is severely worn after repeated friction, resulting in a significant drop in output force
Friction dampers often have residual deformation, which cannot meet the requirements for some important structures to be put into use immediately after earthquakes

Abstract

The invention discloses a rotating type friction energy dissipation wall, and relates to the field of seismic reduction control of building structures. The invention aims at providing a friction energy dissipation wall capable of realizing energy dissipation-seismic reduction by using displacement deformation in a structure under the action of an earthquake. In order to realize the aim, the rotating type friction energy dissipation wall is characterized in that a movable frame is connected between upper and lower beams of a building; a plurality of transverse friction steel plate groups and aplurality of longitudinal friction steel plate groups are arranged in the movable frame, and the horizontal friction steel plate groups and the longitudinal friction steel plate groups are overlappedin a crossed way; movable friction nodes are arranged at the overlapped parts. When the building structure is subjected to a horizontal earthquake action, the movable frame is deformed, the friction nodes are rotated, and energy dissipation is achieved by means of mutual friction of transverse friction steel plates and longitudinal friction steel plates. The stability of friction between the friction steel plates can be maintained by means of friction plates in the friction nodes, and hard gaskets in the friction nodes can prevent the friction steel plates from being damaged, so that the service lives of the friction steel plates are prolonged.

Description

technical field [0001] The invention relates to the field of damping control of building structures. Background technique [0002] Earthquake disasters in my country are widely distributed and destructive, often causing immeasurable losses to society and the country. By introducing energy dissipation devices into the building structure, increasing the stiffness and (or) damping of the building structure can achieve the purpose of reducing structural displacement and damage. Therefore, as an effective, economical and safe engineering control technology, energy dissipation and shock absorption technology is more and more favored by engineering circles. [0003] Frictional energy-dissipating dampers have the characteristics of high energy consumption, low cost, and easy installation and maintenance. Using the relative displacement of the structure under the action of earthquake or strong wind load, the energy-dissipating damper is driven to consume the energy generated by the ...
