有机玻璃框架隔震模型的振动台试验研究

TESTING STUDY ON THE DYNAMIC CHARACTERISTICS OF ORGANIC GLASS MODEL OF AN EARTHQUAKE ISOLATION FRAME

提出一种新型隔震体系 (已获中国专利权 ,专利号 :912 0 2 45 3.4) ,经试验表明可阻断 90 %的地震力 ,且施工简便、造价极低、不需维修 ,适用于震区多。

The isolation of earthquake will eventually replace the resistance to earthquake. This seems to be an irreversible trend. However, almost all earthquake isolation devices share the same defects and disad vantages: inefficiency, high cost and difficulty in construction. To solve the problems, a new type of earthquake isolation(E I) device is developed, which has gained the patent right in China. The new E I device is entirely different from the conventional ones in terms of its manufacture, installation and service. The dynamic test of its organic glass model shows that 90 percent of seismic force can be isolated. In addition, its convenience in construction, low cost and no need of maintenance in service make it most suitable for the rigit frame structures in seismic regions.
