【摘要】 文章介绍了粘滞阻尼器减震结构时程分析中各参数物理意义及取值方法。建议按阻尼力输出一致的原则采用线性阻尼系数换算非线性阻尼器的阻尼系数,并作为初始参数进行消能结构的时程分析。最后,以四川某教学楼的减震设计为例,分析结果表明,按文章建议的参数估算值与最终确定的阻尼器参数较为接近,减少了由于参数初选的盲目性带来的反复试算过程。更多还原

【Abstract】 This paper mainly introduced the physical meaning and calculating method of the parametres that used in time-history analysis of structures with viscous dampers. The initial damping coefficient of nonlinear damper used in time-history analysis is suggested to be converted by the linear damping coefficient based on the same damping force output. In the end,a eneregy-dissipating design of one teaching building in Si Chuan is provided.Result shows that the parameter calculated by the way provised by this paper is closed to the ultimate parameter.The method provised can reduce the trial calculation caused by the cecity of parameter selection.更多还原
