变刚度钢管混凝土短柱足尺隔震装置的伪静力试验研究

摘要

在总结目前基础隔震缓冲限位装置现状的基础上，提出了梯队式变刚度钢管混凝土短柱基础隔震装置。通过足尺试件的伪静力试验研究，表明本文装置具有良好的隔震性能，能够起到一次强震时缓冲限位保护和多次强震时二次保护的作用。%On the basis of the stat-of-the-art of protective buffers for base isolation, the step-stiffnessbase isolator of concrete filled steel tubular short column is put forward. Through out a full scalepseudo-static test, the result demonstrates that the device can protect the safety of isolation layer, andalso can provide a secondary defense to the next impact.
