【摘要】 通过线性化等效原理,将消能减震结构中的消能部件等效为框架柱,将非线性分析转化为线性分析,得到消能部件附加给结构的有效阻尼比。对工程实例进行了线性化等效分析和非线性对比分析。研究结果表明:线性化等效分析方法可以准确地得出消能部件附加给结构的有效阻尼比,无论是层间位移角还是层剪力,两种分析方法得出的结果都符合较好,通过"附加有效阻尼比"修正的结构的线性分析与含有消能减震部件的非线性分析得出的结果一致。更多还原

【Abstract】 According to the linear equivalence principle,the energy dissipation component in the energy dissipation structure was equivalent to the frame column to transform the nonlinear analysis to linear analysis and calculate the effective damping ratio provided by the energy dissipation component.Finally,based on a real engineering example,linear equivalence analysis and nonlinear comparative analysis were carried out.Analysis results show that: the effective additional damping ratio can be obtained accurately by the linear equivalence analysis method.Comparative analysis shows that: for both the inter-story drift and the story shearing force,the two calculation results agree well with each other.The linear analysis results of structure modified by the additional effective damping ratio are consistent with the nonlinear analysis results of energy dissipation structure.更多还原
