Base isolation technology is an important way to increase the seismic performance of buildings. This paper proposed that steel balls could be used as Rolling Friction Bearing (RFB) to form a Combined Isolation Bearing (CIB) with Lead Rubber Bearings (LRB). The seismic response of a building with CIB were calculated by numerical analysis method, and the isolation effect was investigated through comparing the seismic shear forces of the structure before and after base-isolated. Research results showed that setting the CIE, the seismic response of upper structure could be reduced greatly, and the coefficient of seismic isolation could be about 0.4 under the earthquake of 7 degree. Furthermore, the CIB was more effective in isolation than that made up of LRB only. |
