摘要
本文提出了一种钢管混凝土短柱隔震支座,通过伪静力试验测定了短柱支座的恢复力特性,给出了有关恢复力的某些特征参数的表达式;对一座七层砌体房屋进行了非线性地震反应分析,考察了短柱支座的特性及其隔震效果;通过模型振动台试验,进一步验证了短柱支座的隔震效果和计算模型的准确性。
A new base-isolation device with concrete-filled steel tubular short columns is proposed in this paper.Through pseudo - static test of the device the restoring force hysteresis curve was meas ured and its characteristic parameters were given. The inelastic analysis of earthquake response of a 1:4 scale 7 -story brick building was,performed. Finally, 6ased on the results of a model test on shaking table, the isolation effects of the device and the effectiveness of the analysis model proposed were examined.
