Description
Technical field
The utility model relates to building fields, particularly relate to a kind of Self-resetting bean column node and steel knot based on SMA bar
Building is built.
Background technique
Frame structure is the citation form in more, high-level structure, and bean column node is the basic unit of frame structure.Frame knot
Structure central sill Column border node will transmit axle power, shearing and moment of flexure, and power transmission mechanism is complicated.Geological process be influence building using it is safe with
One key factor of service life, and frame structure building bean column node plays pass to response of the building under geological process
Keyness effect.
In order to improve the anti-seismic performance of building, the bean column node of early stage is based on bolt weldering mixed node.This node due to
In weld, there are serious stress to concentrate, and tends to occur brittle failure under geological process.The ribbing in traditional bolt weldering mixed node
Or plate is covered to which the reinforcement end node formed makes plastic hinge under geological process, improve its anti-seismic performance.But
This node due to beam end rigidity increasing and need additionally to increase column section, economic effect is bad.Buckling-restrained node is logical
Cross dissipative cell enter surrender and dissipation seismic energy, meanwhile, node is effectively increased to the constraint of buckling component and is back and forth being made
Ductility under has preferable anti-seismic performance.But such node has biggish residual deformation after shake, this will be dramatically increased
The difficulty and cost repaired after shake.
In recent years, with dissipative member and presstressed reinforcing steel or marmem (Shape Memory Alloys, SMA)
Start to emerge in large numbers for the Self-resetting node of component part.Self-resetting node has good Hysteresis Behavior under geological process, can have
Imitate earthquake energy.And after shake, such node and its building can automatically revert to initial position, no residual deformation, thus
It offers convenience for the reparation of building.The Self-resetting node being suggested at present mainly includes prestressing force Self-resetting node and shape note
Recall two class of alloy Self-resetting node.
Prestressing force Self-resetting node provides energy dissipation capacity by dissipative cell, provides Self-resetting energy by the pretension of presstressed reinforcing steel
Power.Since prestressing force Self-resetting node needs pretension muscle, causes it to construct and construction technology is complex, node nominal yield
Rigidity is larger afterwards, and nodes domains beam cross-section also needs accordingly to expand.By the reciprocal loading effect of geological process, pretension muscle can also go out
It now relaxes, loses initial stiffness after undergoing small deformation or earthquake load removal again so as to cause node.
Martensite-austenite phase transition characteristic of the shape memory alloy self-resetting node based on shape memory alloy material itself
Realize energy-dissipating property and Self-resetting performance.But existing shape memory alloy self-resetting node is mostly with SMA silk material or SMA bolt
Main, construction is by shape memory alloy material only based on by pulling force.When SMA member peak deformations are excessive under big shake and enter
When strain, which will generate residual deformation to make node lose initial stiffness when undergoing small deformation again.Equally, low temperature
Lower Shape Memory Alloy member will degenerate and show the behavior of generic metallic component, undergo again after causing node to undergo moderate finite deformation
Initial stiffness is lost due to the influence of residual deformation when small deformation.
