And the shear-bearing ratio is less and the cooperative working perform¬ance is poorer, with fixed connections between coupling beams and the RC core tube and hinged connections between coupling beams and RC columns or the hinged connections of the two ends.

Full textAbstract
In this paper, the 30-storey composite structures with outer steel-concrete composite frame and inner RC core tube were studied. The aseismic behaviors of the four structural models with different connections of coupling beams were analysed And behaviors of the deformation and the bearing force were coMPared. The results show that the shear-bearing ratio is laiyer and the cooperative working performance is better, with hinged connections between coupling beams and the RC core tube and fixed connections between coupling beams and RC columns or the fixed con¬nections of the two ends. And the shear-bearing ratio is less and the cooperative working perform¬ance is poorer, with fixed connections between coupling beams and the RC core tube and hinged connections between coupling beams and RC columns or the hinged connections of the two ends. By discussing the behaviour of the structures, some conclusions can be help for the design of this kind of structure.
