Description
Technical field
The present invention relates to Self-resetting energy dissipation brace technical fields, and in particular to stacked Self-resetting energy consumption branch in a kind of assembling
Support.
Background technology
China is an earthquake-prone countries, and earthquake causes the damage of building even to collapse, and is brought substantial amounts of
Casualties and economic loss.China's current seismic design specification uses Ductility Design thought, passes through the elastoplasticity of structural elements
Earthquake energy is deformed, expenditure of construction is reduced while structural seismic capacity is improved.But after shake, the residual deformation of component
The normal use of structure can be influenced, while brings the rehabilitation expense of great number or even structure can only be pushed over to reconstruction.It is asked to solve this
Topic, researcher propose to add energy dissipation brace system in structure, are supported when earthquake occurs and play energy consumption effect, dissipation seismic energy
Amount protects main member, and reduces structure relative storey displacement angle.The structural seismic capacity of additional energy dissipation brace is improved,
But residual deformation angle is still a problem, therefore researcher proposes Self-resetting energy dissipation brace on the basis of energy dissipation brace,
This residual deformation that structure can be decreased or even eliminated while be supported on energy consumption, the time required to reducing structure repair and takes
With.
Support can be divided into according to working method and design feature：Common support, anti-buckling support and Self-resetting energy dissipation brace.
Common support is consumed energy using the surrender of Low Yield Point Steel, and anti-buckling support phase is more excellent to common support performance, is eliminated common
The asymmetric problem of tensile and compressive property is supported, dissipative system is combined by Self-resetting support with Self-resetting system, has excellent consumption
Can ability and self-resetting capability, Self-resetting system is mainly by deformed bar or the novel intelligent material group with reset capability
Into.
From working performance, more than several be supported by following features：Common support slenderness ratio is larger, and when compression is easy
Buckling causes the reciprocal poor performance of its tension and compression, and hysteresis loop is not asymmetric, full, and energy dissipation capacity declines to a great extent after compressive buckling,
It is difficult to effectively to consume earthquake and is passed to energy, meanwhile, under big shake effect, support is subject to reciprocating load, and component is in itself and connection
System is susceptible to destruction so that common support functional reliability is very low；Anti-buckling be supported on the basis of common support increases about
Beam mechanism, constraint inner tube energy consumption section ensure that tensile and compressive property etc. of support is full to, hysteresis loop, there is very strong energy dissipation capacity, but
The problem of this support system is maximum is to surrender under geological process, and there are larger residual deformations after shake so that reinforcing is repaiied
Multiple difficulty, which increases or even exists, is difficult to the situation repaired, and causes serious economic loss；Self-resetting support has reset function,
It spontaneous can be resetted in its normal work stage, this characteristic can decrease or even eliminate the residual deformation of structure, reset system
System generally use marmem or deformed bar.The elasticity of marmem is good, has self-resetting capability, can be real
The Self-resetting now supported, but Properties of Shape-Memory Alloys is affected by temperature so that the feasibility of the support in practical applications
It substantially reduces；The flexible deformation of deformed bar is small, limits the application of the support system.
From structure composition：Common support and buckling-resistant support structure form are simple, assembled position generally use weldering
Realization is connect, has residual deformation and residual stress；Self-resetting support construction using marmem or presstressed reinforcing steel is usual
Equipped with inner tube and outer tube, resetting apparatus and rubbing device are arranged between inner and outer pipes, while reasonable Arrangement is needed to reset system, therefore
Self-resetting support structure is complicated, and connecting portion is mainly realized by welding, and be easy to cause residual deformation and residual stress.
Accordingly, it is desirable to provide stacked Self-resetting energy dissipation brace in a kind of assembling, using pre-compressed spring as a kind of reset material
Material consumes energy in combination with friction plate, and the collaborative work for resetting system and dissipative system so that the hysteresis loop of the system is full, residual
It is remaining to be deformed into zero, there is excellent reseting performance and energy-dissipating property, it is on the other hand complicated to solve other Self-resetting support structures
And the problem of needing welding, propose stacked Self-resetting energy dissipation brace in assembling.

The shortcomings that being affected by temperature, proposes stacked Self-resetting energy dissipation brace in assembling, and component species is few, and structure type is simple, processing
It is convenient, it is easy to mass production, assembly line processing.System stiffness can be changed by adjusting spring specification simultaneously, by changing
The energy consumption of system can be changed by becoming dissipative system parameter, have good controllability, can extensive use.
