摘要
根据对6种不同类型的结构-设备组合模型体系在多维地震波作用下的振动台试验研究结果,具体分析了结构-设备组合体系的动力特性、结构与设备的抗震性能、对称结构体系与非对称结构体系的地震反应差别等问题,总结了结构-设备动力相互作用的一般特点。对结构-设备组合体系的抗震设计与进一步理论研究提出了若干建议。
Based on the analysis for the shaking table tests of six space structure-equipment model systems, a series of characteristics of dynamic interaction between structures and equipment are investigated. It is shown that the change of the frequency spectrum of the compound system is a basic reason which leads to the dynamic response difference among different structural systems. The existence of equipment intends to reduce the peaks of the response spectrum and widen the spectrum. The differences of earthquake response for symmetic structural system and asymmetic structural system are summarized. Some useful suggestions on seismic design of structure-equipment systems are presented.
