摘　　要：本文提出了一个近似分析具有滞迟耗能装置的高层建筑的方法。结构被模拟为一个具有滞迟非线性支座的悬臂梁。其控制方程由Ritz法导出,用等效线性化方法分析。此方法很省机时,故可方便地用于分析不同参数对响应的影响。数值计算结果显示,使用钢丝绳隔振器加粘弹性阻尼层有较好的减震效果,故推荐它作为一种抗震耗能装置。An approximate method is presented to analyse tall building structures with added hysteretic energy dissipation devices. The structure being analyzed is modeled as a cantilever beam on hysteretic nonlinear supports. Its governing equation is derived by using Ritz method and linearized in each iterative step based on an equivalent linearized method. This method is relatively inexpensive in computation and therefore allows assessment of effects of various parameters on responses. Numerical results show that the use of wire-cable isoslator combined with visco-elastic damping layers is a good example of energy dissipation device,so it is recommended as a novel aseismic mechanism.
