摘要
为了研究隔震层对整个隔震结构和上部结构的有效质量系数的影响,对双质点以及多质点隔震结构和其上部结构的振型参与系数以及有效质量系数进行了计算机模拟分析.分析表明:无论双质点还是多质点隔震结构,当隔震结构有效质量系数达到0.9时,隔震层上部结构的有效质量系数大于0.9,在隔震层上部结构计算时其有效质量系数应相应地提高.
In order to study the influence of isolating layer on the whole isolating structure and its upper structure, the vibration mode participation coefficient and effective mass coefficient of double mass particle and multi-massparticle isolating structure were analyzed by computation. The results of analyses show wether the isolating structure is the double mass particle or multi-mass-particle the isolating structure effective mass coefficient reaches 0.9, and the effective mass coefficient of isolating layer upper structure exceeds 0.9, the effective mass coefficient must be correspon dingly increased in the design of upper structure.
