Abstract：The Kunming new international airport terminal is one of the world’s largest seismic isolation buildings at present. The layout scheme of the seismic isolation layer is described in detail. The finite element model of the terminal is established and the dynamic responses are also analyzed. The shaking table test is carried out for the Kunming new international airport terminal. The scale factor of the model structure used in the test is 1/60. And the layout of the seismic isolation layer is also simplified. The results show the vibration-reduction effects of the seismic isolation building are about 50%. Finally, the seismic performances of the prototype structure are analyzed. Dynamic characteristics, acceleration responses and displacement responses of the prototype structure are investigated under different levels of earthquake. Compared with the shaking table test’s results, it is shown that the finite element analysis results are agreed well with the experimental results. The Kunming new international airport has clear isolation mechanism and good isolation effect with the theoretical and experimental proof. It is feasible and effective for applying the base isolation technology to long-span structures.
