Description

Stacked Self-resetting energy dissipation brace in a kind of assembling
Technical field
The present invention relates to Self-resetting energy dissipation brace technical field, be specifically related to stacked Self-resetting power consumption in a kind of assembling Support.
Background technology
China is an earthquake-prone countries, and earthquake causes the damage of building even to collapse, brings substantial amounts of Casualties and economic loss.China's current seismic design specification uses Ductility Design thought, by the elastoplasticity of structural elements Deformation earthquake energy, reduces expenditure of construction while improving structural seismic capacity.But after shake, the residual deformation of component The normal use of structure can be affected, bring the rehabilitation expense of great number simultaneously, even structure can only be pushed over reconstruction.Ask for solving this Topic, research worker proposes the most additional energy dissipation brace system, supports and play power consumption effect, dissipation seismic energy when earthquake occurs 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, and therefore research worker proposes Self-resetting energy dissipation brace on the basis of energy dissipation brace, This be supported on power consumption while the residual deformation of structure can be decreased or even eliminated, reduce structure repair required time and take With.
Support and can be divided into according to working method and construction features: common support, anti-buckling support and Self-resetting energy dissipation brace. Common support utilizes the surrender of Low Yield Point Steel to consume energy, and the relatively common support performance of anti-buckling support is more excellent, eliminates common Supporting the asymmetric problem of tensile and compressive property, Self-resetting supports and dissipative system is combined 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 Become.
From service behaviour, above several supports have following features: common support slenderness ratio is relatively big, easy during pressurized Flexing, causes the reciprocal poor performance of its tension and compression, and hysteresis loop is asymmetric, the fullest, and after compressive buckling, energy dissipation capacity declines to a great extent, It is difficult to effectively consume the incoming energy of earthquake, meanwhile, under big shake effect, supports by reciprocating load, component itself and connection Destroying easily occurs in system so that common support functional reliability is the lowest;Anti-buckling be supported on common support on the basis of increase about Bundle mechanism, constraint inner tube power consumption section, it is ensured that the tensile and compressive property of support etc. are full to, hysteresis loop, have the strongest energy dissipation capacity, but This support system maximum has a problem in that under geological process surrenders, and there is bigger residual deformation so that reinforce and repair after shake Multiple difficulty increases, and even there is the situation being difficult to repair, causes serious economic loss;Self-resetting supports has reset function, Can spontaneous reset in its normal work stage, this characteristic can be decreased or even eliminated the residual deformation of structure, its system that resets System generally uses marmem or deformed bar.The elastic of marmem well has self-resetting capability, can be real The Self-resetting now supported, but Properties of Shape-Memory Alloys temperature influence so that this support feasibility in actual applications It is substantially reduced;The elastic deformation of deformed bar is little, limits the application of this support system.
From structure is constituted: common support is simple with buckling-resistant support structure form, assembled position generally uses weldering Connect realization, have residual deformation and residual stress;The Self-resetting supporting construction using marmem or presstressed reinforcing steel is usual It is provided with inner tube and outer tube, between inner and outer pipes, arranges resetting means and rubbing device, simultaneously need to reasonable Arrangement reset system, therefore Self-resetting support structure is complicated, and connecting portion is mainly realized by welding, easily causes residual deformation and residual stress.
Accordingly, it is desirable to provide stacked Self-resetting energy dissipation brace in a kind of assembling, pre-compressed spring is used to reset material as one Material, consumes energy in combination with friction plate, and reset system and the collaborative work of dissipative system make the hysteresis loop of this system full, residual More than be deformed into zero, there is excellent reseting performance and energy-dissipating property, on the other hand complicated for solving other Self-resetting support structures And need the problem welded, stacked Self-resetting energy dissipation brace in assembling is proposed.
Summary of the invention
The technical problem to be solved in the present invention is to provide stacked Self-resetting energy dissipation brace in a kind of assembling, solve existing commonly The tension and compression supported are asymmetric, hysteresis loop is the fullest, has residual deformation, shape memory alloy properties under anti-buckling support geological process The shortcoming of energy temperature influence, proposes stacked Self-resetting energy dissipation brace in assembling, and component kind is few, and version is simple, processes Convenient, it is easy to mass production, streamline is processed.System stiffness can be changed, by changing by regulation spring specification simultaneously Become dissipative system parameter and can change the power consumption of system, there is good controllability, can extensively apply.
