In the large public buildings such as shop, exhibition center and airport building.Since long-span space Single-layer Spherical Lattice Shell Structure is mainly answered
For frequent activity, densely populated place public building in, since load or environment change during construction or use, by
Earthquake, disaster caused by a windstorm etc. can cause the force modes, force path and stress distribution of structure to change, and then cause structure broken
It is bad, and Reticulated Domes, since redundancy is relatively low, the ability for resisting continuous collapse is also weaker, when structure partial destroys
Afterwards, structure overall collapse may be caused to destroy quickly.It is one that structure collapse resistant capacity is improved by way of adding damper
The reasonable effective method of kind.Currently, mainly traditional tuned mass damper, visous damping is arranged on large span spatial structure
The oscillation damping and energy dissipatings such as device.These damper generally existing oil leaks, cost is high and the problems such as needing later maintenance.There is an urgent need for research and development to be suitable for
The high-performance vibration reduction damper of long-span space Single-layer Spherical Lattice Shell Structure.
Marmem (SMA) is quick with application as research of one of the intellectual material in terms of the antidetonation of civil engineering
Development.SMA has unique shape memory effect and super elastic characteristics.Super-elasticity is one of its key property, i.e. SMA generate compared with
Big deformation, the shape that can be returned to after external force is removed before deformation, and nonlinear characteristic, meeting is presented in strain-stress relation
Generate Dissipated energy.It is worth noting that, the above-mentioned load-deformation curve with apparent hysteretic characteristics is by SMA internal solids phases
Caused by change process, therefore the damage of material will not be led to.The damper designed using super elastic shape memory alloy effect,
Durability and corrosion resistance and good, service life is long, allows large deformation and deform to restore.

Between be provided with SMA, the SMA application prestressing force, and being anchored at respectively by first fixture and the second fixture described
On first connecting plate and the second connecting plate.
Further, two pieces of second connecting plates are located at same axis with two wing plates of first connecting plate respectively.
Further, the end of two wing plates of first connecting plate is circular configuration, and radius is equal to the round friction
The radius of piece.
Further, bolt hole is offered on the wing plate of first connecting plate, first connecting plate passes through common spiral shell
Bolt is closely connect across bolt hole with first fixture；Second connecting plate offers bolt hole, second connecting plate
It is closely connect with second fixture across bolt hole by plain bolt.
The beneficial effects of the invention are as follows：
A kind of SMA silks-frcition damper suitable for Reticulated Domes of the invention, when structure is by geological process,
Damper will be made to deform, consumed energy with structural friction to generate the energy consumption of SMA deformation of filament.Compared to other types damper,
It is suitable for Single-layer Spherical Lattice Shell Structures, are easily installed, and have good energy dissipation capacity and job stability, while after shake easily
In replacement.
Damper of the present invention is equipped with friction plate and SMA between the first connecting plate and the second connecting plate.When small shake, this resistance
Buddhist nun's device stress is less than force of sliding friction, and damper provides rigidity, and the first connecting plate is deformed to pull SMA to be deformed
Energy consumption；When big shake, frictional force is overcome, and opposite sliding occurs for damper structure layer, at this time friction energy-dissipating and the energy consumption of SMA deformation of filament
It works together.Damper stress of the present invention is clear, simple in structure, and easy to process, installation is replaced.
