结构-设备互动减震体系的地震反应分析

Seismic Response of Structure-Equipment Mutual Affecting Damping System

根据建筑物与设备在地震力作用下的相互作用,提出了将建筑物内部的设备作为减震子结构,建筑物作为主结构的互动减震体系.研究了这种互动减震体系的减震机理以及在地震力作用下的反应.结果表明,通过调整子结构的质量、刚度及位置,可以有效地衰减结构的地震反应.

Based on the mutual affecting between structure and interior equipment, a new kind of system was presented. In this system, structure is considered as main-structure, and interior equipment is regarded as sub-structure. Its mechanism of reducing vibration and seismic response were studied by means of dynamic time-history analysis. The result indicates that the seismic response can be effectively reduced by adjusting the mass, stiffness and position of sub-structure.
