摘要
传统的变刚度控制系统可以有效地抑制结构在地震激励下的动力响应,但是,现有的变刚度装置仅能在很小的范围内改变结构的周期,而且也不利于抑制结构的加速度反应。为了克服这一局限性,提出了一种新型的半主动变刚度(ISAVS)控制系统,并通过数值模拟验证了它的有效性。
The conventional semi-active variable stiffness systems may be effective for vibration control of buildings subjected to seismic excitations, existing variable stiffness devices can only vary structural periods within a narrow range, and the device is also adverse to decrease the dynamic acceleration response of structures. In order to overcome this limitation an innovative semi-active variable stiffness (ISAVS) system is presented in this study, and numerical simulations verify its validity.
