摘要
通过结构—设备等价体系频域传递函数的比较分析,讨论了结构—设备动力相互作用对结构绝对动力反应与相对动力反应的影响。着重指出,这种影响是增大还是减小结构的动力反应取决于地震动频谱特性与结构、设备固有频率及质量比的关系。提出了利用场地土卓越周期判定上述影响的简便方法。
Through comparative analysis of the frequency transferring function, the effects of the struc- ture-equipment dynamic interaction on absolute response and relative response of the structure are studied in the paper. Tt is stressed that whether the effects would magnify or diminish the dynamic response of the structrue is determined by the relationship between the frequency property of the seis- mic wave, the frequency of the structure, tbe frequency of the equipment and the equip- ment-structure mass ratio. A brief method using the site predominant period is put forward to assess the effects.
