Description
Technical field
The invention belongs to civil engineering structure design field, relate to a kind of round steel pipe binding type steel concrete column and steel beam joint structure.
Background technology
In steel-concrete combined structure, the vertical load-bearing pillar of tradition mainly comprises steel core concrete column and profile steel concrete column two kinds of forms.These two kinds coupled column bearing capacity is high, anti-seismic performance good, cost is moderate, by structural engineer is favored, becomes the first-selected component form of compression ratio of frame columns for high building.But along with the accumulation of engineering practice and the development of high strength structure material, they show certain limitation gradually.The ductility of concrete filled steel tube is better than steel concrete, but steel pipe just produces effective effect of contraction to core concrete after entering elastic-plastic phase in steel core concrete column, binding effect is not strong, and steel pipe and concrete shared axial load easily cause steel pipe Plate buckling, cause pillar anti-seismic performance to decline.When steel core concrete column is connected with reinforced concrete beam, node often adopts through ribbed and outer annular-stiffer formula two kinds, and design of node is complicated, and difficulty of construction is large.Then need in profile steel concrete column to establish reinforcing cage to ensure the acting in conjunction of concrete and shaped steel, cause cross section shaped steel and reinforcing bar densely distributed, concreting and difficulty of vibrating, and concrete is tied deficiency in profile steel concrete column, cause limit value of axial compression ratio on the low side, steel and concrete supporting capacity can not be made full use of.
In long-term research work and engineering practice basis, Zhou Xuhong etc. propose a kind of Novel combined column form of structure-steel tube binding type steel concrete column.The outside steel pipe of steel tube binding type steel concrete column disconnects at bean column node place, and not by joint cores, steel pipe does not directly bear longitudinal load, only plays effect of contraction to core concrete.Steel tube binding type steel concrete column inherits the advantage of steel core concrete column and profile steel concrete column, and steel pipe is applied with continuous constraint effect to concrete, improves concrete compressive strength and improves concrete ductility; The existence of shaped steel improves the shear resistance of pillar; Concrete existence compensate for the shortcoming of shaped steel and the easy flexing unstability of empty steel pipe.Based on the mechanical property that steel tube binding type steel concrete is superior, Chinese scholars conducts in-depth research it in recent years.Research shows, the resistance to compression of steel tube binding type steel concrete column, shear-carrying capacity are high, and anti-seismic performance is superior, and stratified deformation ability is strong, and fire resistance is good, easy construction, can make full use of Materials with High Strength performance, is a kind of combining structure form with broad development prospect.
At present, the concrete research of steel tube binding type steel is mainly concentrated on to static(al) and the anti-seismic performance of component, system is not yet goed deep into the research of steel tube binding type steel concrete column-steel beam joint and carries out.Concrete frame joint is the important component part of frame construction, and the mechanical property of joint cores plays critical effect to the integral rigidity of structure and stress performance.All previous earthquake shows, node area is the position be easily damaged under geological process, and node area supporting capacity or deformability deficiency are the major reasons causing structural deterioration.The joint forms such as the through ribbed of conventional steel beam column built from concrete and outer annular-stiffer formula, all must rely on steel pipe Transfer of Shear in varying degrees, thus make steel pipe directly bear longitudinal force.And when adopting steel tube binding type steel concrete frame trestle, 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 cannot be continued to use.Promote the new structural members that this stress performance of steel tube binding type steel concrete column is good, must the node that adapts with it of research and design.
In sum, the excellent in mechanical performance of steel tube binding type steel concrete column, has wide application prospect.But because post outside steel pipe disconnects in node area, essential distinction is had with the force modes of traditional group zygostyle, the conventional node of outside steel pipe Transfer of Shear is relied on to continue to use in various degree, and the node being applicable to steel tube binding type steel concrete column studies not yet system expansion, almost blank, seriously constrain the concrete application & development of steel tube binding type steel.
Joint behavior research is key scientific problems urgently to be resolved hurrily, therefore, system further investigation steel tube binding type steel concrete column and steel beam joint stress performance, propose to meet " strong node, weak component " design principles, bearing capacity is high, good integrity, power transmission is clear and definite, and safe and reliable, the joint form of easy construction is steel tube confinement reinforced concrete structure research aspect key scientific problems urgently to be resolved hurrily.
