Description
Technical field
The invention belongs to civil engineering structure design fields, are related to a kind of round steel pipe binding type steel concrete column and steel
Girder connection structure.
Background technology
In steel-concrete combined structure, the vertical load-bearing pillar of tradition mainly includes steel core concrete column and profile steel concrete column
Two kinds of forms.Both coupled column high capacities, anti-seismic performance is good, cost is moderate, is favored by structural engineer, becomes high-rise
The preferred component form of building frame column.But with the accumulation of engineering practice and the development of high strength structure material, they are gradually
Show certain limitation.The ductility of concrete filled steel tube is better than armored concrete, however steel pipe exists in steel core concrete column
Effective effect of contraction just is generated to core concrete after into elastic-plastic phase, binding effect is not strong, and steel pipe and concrete
Shared xial feed easily causes steel pipe Plate buckling, and pillar anti-seismic performance is caused to decline.Steel core concrete column is mixed with reinforcing bar
During solidifying Tu Liang connections, node is frequently with two kinds of through ribbed and outer annular-stiffer formula, and design of node is complicated, and difficulty of construction is big.Shaped steel mixes
It then needs to set steel reinforcement cage in solidifying earth pillar, to ensure the collective effect of concrete and shaped steel, to cause section shaped steel and reinforcing bar densely distributed,
Concreting and difficulty of vibrating, and the constrained deficiency of concrete in profile steel concrete column, cause limit value of axial compression ratio relatively low, it is impossible to
Make full use of the bearing capacity of steel and concrete.
On the basis of long-term research work and engineering practice, Zhou Xuhong etc. proposes a kind of novel compositions rod structure shape
Formula-steel tube binding type steel concrete column.The outside steel pipe of steel tube binding type steel concrete column disconnects at bean column node, obstructed
Joint cores are crossed, steel pipe does not directly take on longitudinal load, only plays effect of contraction to core concrete.Steel tube binding type steel coagulation
Earth pillar inherits the advantage of steel core concrete column and profile steel concrete column, and steel pipe is applied with concrete continuous constraint effect, carries
The high compression strength of concrete and the ductility for improving concrete;The presence of shaped steel improves the shear resistance of pillar;Coagulation
The presence of soil compensates for the shortcomings that shaped steel and empty steel pipe easy buckling unstability.Based on the superior mechanical property of steel tube binding type steel concrete
Can, domestic and foreign scholars in recent years conduct in-depth research it.Research shows that the resistance to compression of steel tube binding type steel concrete column, anti-
High capacity is cut, anti-seismic performance is superior, and stratified deformation ability is strong, and fire resistance is good, easy for construction, can make full use of Materials with High Strength
Performance is a kind of composite structure form with broad development prospect.
At present, the static(al) and anti-seismic performance of component are focused primarily upon to the research of steel tube binding type steel concrete, to steel pipe
System development is not yet goed deep into the research of binding type steel concrete column-steel beam joint.Concrete frame joint is the important of frame structure
Component part, the mechanical property of joint cores play critical effect to the overall stiffness and stress performance of structure.It is all previous
Earthquake shows that node area is the position being easily damaged under geological process, and node area carrier ability or deformability deficiency are
The major reason that structure is caused to be destroyed.The joint forms such as the through ribbed of conventional steel beam column built from concrete and outer annular-stiffer formula, it is different
Steel pipe Transfer of Shear must be all relied in degree, so as to which steel pipe be made directly to bear longitudinal force.And use steel tube binding type steel concrete
During frame column, due to the essential distinction of force modes, steel pipe disconnects in node area, and node area is on the weak side, and conventional node can not be continued to use.
Promote the good new structural members of this stress performance of steel tube binding type steel concrete column, it is necessary to which research and design is mutually fitted therewith
The node answered.
In conclusion the excellent in mechanical performance of steel tube binding type steel concrete column, has wide application prospect.But due to column
Outside steel pipe disconnects in node area, has essential distinction with the force modes of traditional group zygostyle, is passed in various degree by outside steel pipe
Passing the conventional node of shearing can not continue to use, and be unfolded suitable for the node research not yet system of steel tube binding type steel concrete column,
Almost blank seriously constrains the application and development of steel tube binding type steel concrete.
Joint behavior research is key scientific problems urgently to be resolved hurrily, therefore, system further investigation steel tube binding type steel reinforced concrete
Solidifying earth pillar and steel beam joint stress performance, proposition meet " strong node, weak component " design principle, high capacity, and good integrity passes
Power is clear and definite, and safe and reliable, easy for construction joint form, is that steel tube confinement reinforced concrete structure research aspect is urgently to be resolved hurrily
Key scientific problems.
