Vertical channel-section steel (1,2,3,4) is set respectively in T shape concrete profiled pile, vertical channel-section steel (2) is connected with vertical channel-section steel (1) by web member (5,6,7) respectively, be connected with vertical channel-section steel (3) by web member (8,9,10), be connected with vertical channel-section steel (4) by web member (11,12,13,14), thereby form an overall space steelframe.
More than join the concrete profiled column section of tee bar of channel-section steel pen-web framework and join the steel rate 4% ~ 10%.
The invention has the beneficial effects as follows:
The tee bar concrete profiled pile of joining the channel-section steel pen-web framework is by reasonably disposing shaped steel, thereby guarantees that shaped steel and concrete can collaborative works, reaches the supporting capacity that improves common RC hetermorphiscal column and the purpose of anti-seismic performance.Special-shaped column structure can be applied, particularly the highrise building in the above area of seismic fortification intensity 8 degree in the building in highrise building and high earthquake intensity area.
Description of drawings
Fig. 1 joins the tee bar concrete profiled pile schematic diagram of channel-section steel pen-web framework.
The specific embodiment
The tee bar concrete profiled pile of joining the channel-section steel pen-web framework, the transverse shearing force that web member in the skeleton can bear between shaped steel and the concrete has played the effect that is equivalent to peg simultaneously, very favourable to guaranteeing shaped steel and concrete collaborative work, and web member can be between each post limb Transfer of Shear, can prevent the shear lag phenomenon in hetermorphiscal column cross section effectively, because the repeatability of geological process disposes the intersection web member, can improve the anti-seismic performance and the shear-carrying capacity of hetermorphiscal column effectively.The web member that intersects is welded on the both sides of channel-section steel, form a space integral body with channel-section steel, not only having preferably, integral rigidity bears the load of construction stage, simultaneously, web member and channel-section steel form enclosure space inner concrete is played certain effect of contraction, and be very favourable to improving bearing of component and anti-seismic performance.We show by the experimental study result of 7 test specimens: configuration intersection web member is joined the SRC hetermorphiscal column of channel-section steel pen-web framework, and shaped steel and concrete can keep collaborative work, have antidetonation deformability and energy dissipation capacity preferably.
For the supporting capacity that can reach effective raising hetermorphiscal column and the purpose of anti-seismic performance, the steel rate of joining in cross section can not be too low, can not be too high, shaped steel is joined very little, miss one's aim, but shaped steel is joined too much, must cause concrete that the bond stress of shaped steel is reduced, have influence on both adhesion stresss.In conjunction with China's national situation, the cross section is joined the steel rate and is advisable 4%～10%, we are by experimental study, joining the steel rate compares ultimate bearing capacity for the SRC hetermorphiscal column RC hetermorphiscal column identical with section form in this scope and improves and (specifically see Table 1) more than 36%, shaped steel and concrete adhesion strength reach about 2.5MPa, and the slippage between shaped steel and the concrete is less than 0.2mm.
The ultimate bearing capacity of table 1 SRC hetermorphiscal column and RC hetermorphiscal column relatively
The tee bar concrete profiled pile of joining the channel-section steel pen-web framework, in order to guarantee shaped steel and concrete collaborative work better, the longitudinal reinforcement of configuration some and stirrup effect can be better in the cross section, if but the web member quantity of joining the channel-section steel pen-web framework is enough, can no longer need to dispose vertical muscle and stirrup, thus convenient construction.
In order to ensure shaped steel and concrete collaborative work, satisfy the fire prevention of structure, requirement such as anticorrosion, antirust simultaneously, the SRC hetermorphiscal column needs certain thickness of concrete cover, and protective layer thickness can be calculated by following formula to be determined:
c
