Description
Technical Field
The invention belongs to the technical field of civil engineering structure anti-seismic and shock absorption, and particularly relates to a movable composite energy consumption damper adopting a vacuum chuck.
Background
After the earthquake happens, in order to restore the normal production and living order of the disaster area as soon as possible and prevent the damage and the danger of people injury caused by collapse of the earthquake-damaged building in the subsequent frequent aftershocks, the rapid detection and evaluation work must be carried out on the building after the disaster, and safe and reasonable earthquake-resistant reinforcement measures are taken for the earthquake-damaged building with reinforcement significance. Therefore, rapid reinforcement of a severely damaged part becomes a hot point of research, and the adopted reinforcement member is required to have the characteristics of rapid installation and flexible movement besides meeting the structural energy consumption requirement.
At this stage, a common reinforcement method is to install energy-consuming and shock-absorbing devices at certain parts (such as nodes) of the structure to be reinforced to absorb or consume a part of the input energy and minimize possible structural damage. Due to good energy consumption capability and ductility, the anti-buckling supporting device has the characteristics of convenience in construction and installation, economy, flexibility in design, no influence on the attractiveness of a building and the like, and becomes a better choice for the anti-seismic design of a newly-built building and also becomes an important means for the anti-seismic reinforcement of the existing structure.
At present, the Buckling Restrained Brace (BRB) is mainly installed by embedding a gusset plate in a reinforced concrete member to realize rigid connection or hinging. Once the gusset plate position is fixed, the mounting position of the buckling restrained brace cannot be changed. The realization of this kind of connected mode need carry out the preliminary treatment to the structure, and not only the waste time increases the reinforcement cost, makes the structure hookup location more weak more easily and becomes, and the atress is more complicated, and traditional BRB's adjustability is poor, hardly installs fast, wastes time and energy, can not consolidate the structure in the very first time, can cause serious shadow casualties and loss of property, influences going on of earthquake relief work. Meanwhile, the buckling restrained brace only carries out tension and compression energy consumption in the axial direction, and cannot play a role in fully consuming energy under the earthquake action with uncertainty in direction.
Therefore, the application fields and scenes of structural reinforcement and shock absorption can be expanded by the movable damper technology and the implementation mode thereof, and technical support is provided for realizing a flexible structure and a flexible city.
