摘要
对不同隔震层偏心率的基础隔震结构进行了分析,提出了扭转减震系数的概念。通过对比水平减震系数与扭转减震系数,得到如下结论:隔震层偏心率在5%以下时,上部结构水平减震系数要大于扭转减震率;当隔震层偏心率大于5%时,上部结构水平减震系数要小于扭转减震系数,此时结构减震效果不能用水平减震系数来表示。
Analyzed the different isolation layer eccentrictiy of the base-isolated structures,proposed the concept of the torsion damping coefficient.By comparing the horizontal damping coefficient with the torsion damping coefficient,conclusions are drawn： when the isolation layer eccentricity 5%,the damping coefficient of upperstruc ture is greater than the torsion damping coefficient,when the isolation layer eccentricity 5%,the horizontal damping coefficient of upperstruc ture is less than the torsion damping coefficient,the structure damping effect can’t be represented by the horizontal damping coefficient at this time.
