摘要
本文研究粘滞、粘弹、金属屈服和摩擦型等四类与斜撑串联的被动耗能器对结构减振效果的参数影响。首先，建立了结构、耗能器和斜撑共同工作的计算模型；然后考虑不同耗能器的特点，给出了相应的运动方程；第三，通过大量的数值计算，研究了耗能器刚度（或耗能器与斜撑的组合刚度）、屈服位移等参数对结构减振结果的影响，得到了这些参数的最佳取值范围，从而为结构的耗能减振设计提供了基础。
n this paper,parameter influence of passive energy dissipators,viscous,viscoelastic,metallic and frictional ones in series with bracing members,on suppressive effectiveness of structural vibration under earthquake is systematically studied.First of all,a computational model taking account into the interaction of structure,dissipators and bracing members is established.Then,according to the characteristics of different dissipators,the corresponding motion equations of passive energy dissipation systems abovementioned are obtained,respectively.Finally,the in fluence of parameters,such as stiffness and yielding displacement of assembled element of the dissipator with the bracing member,on the suppressive effectiveness of structural vibration is analyzed based on the numerical results and the rational range of parameters is suggested for the design of passive energy dissipation systems.
