In this embodiment, the earthquake-resistant structure includes an earthquake-resistant support 9, a corbel 11, an upper shock-absorbing assembly and a lower shock-absorbing assembly. The earthquake-resistant support 9 is arranged on the lower side of the end of the low-rise building beam 8, the corbel 11 is arranged at the lower end of the earthquake-resistant support 9, and one side of the corbel 11 is fixedly connected to the side of the high-rise building column 1. It is worth noting that an intelligent damper is arranged inside the earthquake-resistant support 9. The intelligent damper is composed of a shape memory alloy, which can automatically adjust its own stiffness and damping characteristics according to changes in the external environment.
[0022] Furthermore, the upper shock-absorbing assembly and the lower shock-absorbing assembly are arranged at the upper end of the corbel 11. Specifically, the upper shock-absorbing assembly and the lower shock-absorbing assembly are both arranged between the high-rise building column 1 and the low-rise building beam 8, and the upper shock-absorbing assembly and the lower shock-absorbing assembly are both arranged on the lower end side of the low-rise building beam 8. At the same time, the upper shock-absorbing assembly is arranged at the upper end of the lower shock-absorbing assembly, and the upper shock-absorbing assembly and the lower shock-absorbing assembly are fixedly connected by a plurality of connecting rods 12.
[0023] In this embodiment, the upper shock-absorbing assembly includes an upper connecting column 3, a spring sheet 4 and a transition plate 5. There are two upper connecting columns 3 and two spring sheets 4, and the two upper connecting columns 3 and the spring sheets 4 are symmetrically arranged with the transition plate 5 as the center. Specifically, the upper connecting columns 3 and the spring sheets 4 are arranged on both sides of the transition plate 5, wherein the ends of the upper connecting columns 3 are connected to the side of the high-rise building column 1 or the side of the seismic bearing 9, that is, the ends of the upper connecting columns 3 arranged on one side of the transition plate 5 are connected to the side of the high-rise building column 1, and the ends of the upper connecting columns 3 arranged on the other side of the transition plate 5 are connected to the side of the seismic bearing 9.

[0024] In this embodiment, the lower shock-absorbing assembly includes a diagonal brace column 2 and a lower connecting column 7, wherein the lower connecting column 7 is arranged at the lower end of the upper connecting column 3, and the upper connecting column 3 and the lower connecting column 7 are fixedly connected by a plurality of connecting rods 12.

At the same time, the unoffset forces can also be gradually dispersed to the diagonal support column 2, the lead rubber support 10 and the elastic connecting rod 13 through the rubber seismic isolation support 6 arranged at the lower end. The dispersed forces will then be transmitted to the high-rise building column 1 and the low-rise building beam 8. Therefore, by consuming the forces layer by layer, the forces caused by the earthquake between the high-rise building column 1 and the low-rise building beam 8 can be reduced, the seismic resistance between the high-rise building column 1 and the low-rise building beam 8 can be increased, and the connectivity between the two can be improved.
