【摘要】 钢结构与砖混或混凝土结构阻尼比不同,轻钢增层结构呈非比例阻尼特征。结合具体工程实例,研究了常数阻尼、Rayleigh阻尼和振型应变能阻尼这3种阻尼计算方法对轻钢增层结构地震反应的影响,分析结果可作为轻钢加层结构抗震设计的参考。更多还原

【Abstract】 The damping ratio of steel structures and RC structures are different,and the storey-adding structure of light-weight steel has non-proportional damping characteristics.Combining with an example of project,the paper do some research on the influence of different damping modes on the seismic response of storey-adding structure of light-weight steel by using three different calculation methods,which are constant damping,rayleigh damping and modal strain energy damping.The results can be used as the seismic design of storey-adding structure of light-weight steel for reference.更多还原
