| 摘 要： | 震害调查表明,建筑结构的地震扭转效应将会加重结构的破坏,甚至造成建筑物倒塌。本文在总结国内外对结构平动-扭转耦联研究的基础上,提出了采用消能支撑减小结构扭转效应的分析计算方法。以单层非对称结构为例,较系统地分析了附加阻尼比、阻尼偏心率和偏心侧阻尼布置率等参数对扭转效应的控制效果,提出了阻尼支撑布置的原则,可用于指导减震结构设计。 |

| Abstract: | Investigation of earthquake damage shows that the torsional responses of building structures would cause structural damage,and even the collapse.In this paper,based on the studies of the coupled lateral-torsional vibration,the analysis and calculation methods to reduce the reverse torsional effect of the structure with damped bracings are suggested.With the single asymmetric structure,systematic analysis of additional damping ratio,damping eccentricity and rate of damping parameters such as layout of the co... |
