The specific embodiment
The SRC hetermorphiscal column of joining the T-steel truss, the transverse shearing force that web member in the truss 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.We show by the experimental study result of 9 test specimens: the SRC hetermorphiscal column of configuration intersection web member T-steel truss, shaped steel and concrete can keep collaborative work until the bearing capacity damage that reaches capacity, the cross section strain meets plane hypothesis, the hysteresis loop of test specimen is full, the antidetonation bearing capacity is high and deformability is big, energy dissipation capacity is strong, has better anti.
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.
