| Abstract: | Study on the seismic isolation theory and method of frame structure based on composite SMA strands- laminate rubber bearings is carried out, motion equations of unidirectional seismic isolation system with three different beatings respectively are established, and the time history analysis of a typical four-floor frame structure under rare earthquake is also conducted. The rusuh shows that, the composite SMA strands-laminate rubber beating is an effective isolation device and the seismic response, such as displacement , velocity and acceleration of the structure with application of the device would be reduced effectively. |
