地震会给人类造成极大的灾害,因而设法提高建设物的抗震能力是工程界十分关心的一个课题,国内外对这方面进行了大量研究并取得了许多显著的成果.其中之一就是在建筑物底部加基础减震器,由多层钢钣—橡胶叠合而成的水平剪切减震器,可以衰减由地面传往上部结构的振动能量,从而提高其抗震能力.近十多年来这种减震器已逐步在工程实践中应用,因为建筑物的基频都比较低,采用这种减震器会导致在风载作用下的不稳定,所以必须同时安装滞后阻尼器或
Earthquakes can cause great disasters to human beings, so trying to improve the seismic capacity of buildings is a topic of great concern to the engineering community. Many studies both at home and abroad have made remarkable achievements. One of them is in the construction At the bottom of the base plus the base shock absorber, a horizontal shearing shock absorber made of multi-layer steel sheet - rubber can attenuate the vibration energy transmitted from the ground to the superstructure so as to enhance its seismic capacity. This shock absorber has been gradually applied in engineering practice, because the building’s fundamental frequency is relatively low, the use of such shock absorbers will lead to instability under the wind load, so you must also install the hysteresis damper or
