摘要:
利用复模态方法,对巨型-子控制结构体系和普通巨型框架结构进行了非平稳地震作用下的对比分析,主框架顶层的位移响应降低了95.70%,加速度响应降低了24.08%;证明这种新的结构体系对地震作用的有效控制,对结构安全性和舒适度均有明显提高.探讨了次框架的剪切刚度与耗能阻尼器的阻尼对结构地震响应的影响,当次框架与主框架的剪切刚度比大于0.15并避开0.4;耗能阻尼器与次框架的首层阻尼比为1.0~3.0,结构的地震响应可以得到进一步的控制,给出的合理范围对结构设计起到了指导性作用.
Abstract:
Using the complex mode method, the giant-sub-control structure system and the ordinary giant frame structure were compared and analyzed under the action of non-stationary earthquakes, and the displacement response of the top layer of the main frame was reduced by 95.70% and the acceleration response was reduced by 24.08%. It proves that this new structural system can effectively control the seismic effect, and significantly improve the safety and comfort of the structure. The influence of shear stiffness of the subframe and the damping of the energy-dissipating damper on the seismic response of the structure was discussed, and the shear stiffness ratio between the subframe and the main frame was greater than 0.15 and avoided 0.4. The first damping ratio between the energy-dissipating damper and the subframe is 1.0~3.0, and the seismic response of the structure can be further controlled, and the reasonable range given plays a guiding role in the structural design.
