摘　　要：本文建议了一种多自由度自动复位基础隔震体系 ,并建立了其计算模型和运动方程。对两质点以滚球隔震模型进行了振动台试验。结果表明 ,与基础固定结构相比 。In this paper,a multi?degree base isolation system with restoring property is proposed. The shaking table tests of two lumped mass base isalation model with rollers are carried out,and the computation model and equation of motion for such system are presented.Test results show that the rolling base isolation is very effective for reduction of seismic response of superstructure in comparison with the fixed base structure.
