随着建筑物抗震设计的安全性和适用性的要求日益提高,传统抗震设计方法存在诸多的局限性,而结构振动控制理论是解决该类问题的一种较好的新方法。理论分析、模型试验和试点工程实践均表明,合理的隔震结构设计可使地震反应降到相应传统抗震结构响应的40%以下,而且在地震设防区,尤其是高烈度设防地区,隔震技术可以作为一种有效方法突破层数限制。为了研究隔震技术在高层结构中的应用,在对高层非线性隔震结构进行隔震效果分析的基础上,与传统抗震结构地震反应进行了对比,并分析了高层隔震结构在高振型、大高宽比以及平移-扭转耦合效应作用对高层非线性隔震结构的影响,提出了高层隔震结构在应用上存在的问题及改进策略。
With the increasing demand for the safety and suitability of seismic design of buildings, the traditional seismic design methods have many limitations, and the theory of structural vibration control is a better new method to solve such problems. Theoretical analysis, model tests and pilot engineering practice all show that reasonable seismic isolation design can reduce the seismic response below 40% of the corresponding traditional seismic response, and in seismic fortification areas, especially in areas with high intensity of fortification, isolation technology Can be used as an effective way to break the layer limit. In order to study the application of isolation technology in high-rise structures, based on the analysis of the isolation effect of the high-rise nonlinear isolation structure, the seismic response is compared with that of the traditional earthquake-resistant structures. , Large aspect ratio and the effect of translational-torsional coupling effect on high-rise nonlinear isolation structure, the problems existing in the application of high-rise isolation structure and the improvement strategies are put forward.
