| 摘 要： | 本文提出了变刚度钢管混凝土短柱隔震装置的设想，进行了足尺隔震装置滑动摩擦、滚动摩擦两种方案的伪静力试验，结果表明本文装置具有较好的耗能能力、延性及变刚度特性，能够在中小震时起到较好的隔震效果，在大震时避免隔震层产生过大位移及隔震元件失稳现象的发生。

| Abstract: | The variable stiffness base isolator with concrete filled steel tubular short column is put forward, and pseudo-static tests of the prototype for sliding motion and rolling motion are carried out. The research demonstrates that the energy dissipation, ductility and variable stiffness of the isolator are satisfactory. The isolator is stable and very effective at various earthquake levels. |
