摘要
从用柔度矩阵表示的频率方程出发,根据上部结构周期、总基底剪力、顶点位移相等的等效准则,推导出可用于规则型高层隔震结构的的三自由度等效模型,并且通过数值模拟给出了模型参数的简化计算公式.总结得出了用于高层隔震结构的实用设计方法,通过工程实例说明了设计步骤.设计实例表明,实用设计法可不依赖于计算机,通过振型分解反应谱法的手工计算,即可对原结构进行隔震设计和验算.
From frequency equation represented by flexibility matrix, according to equivalent rules of equal structure period, total base shear and top - point displacement, three - degrees equivalent model for regular high -rising isolated structure was deduced, and simplified computing formula for model parameters has been given after numerical analysis. Practical design method for high - rising isolated structure was proposed, and design process of the method was shown by a project example. Design example indicates the practical design method can be applied in isolation design and checking by using handwork calculation of response spectrum analysis method without the computer.
