高层结构等效线性化方法研究

Error Separation and Method Improvement for Equivalent Linearization of Core-outrigger Structure

等效线性化可将结构的非线性行为转化为线性行为,易于结构工程师掌握与应用.在前人研究的基础上,将该方法用于高层结构中,比较了2种等效线性化方法与弹塑性时程分析结果的差别.结果表明,等效线性化方法的多条地震波平均结果的误差是在工程上可接受的.

Equivalent linearization method can transfer nonlinear behavior of structures to linear behavior which can be easily grasped by engineers .Based on previous research , equivalent linearization method was used in high-rise structures and two kinds of equivalent linearization methods were compared with nonlinear time his -tory analysis .It is shown that the average result of equivalent linearization method can be accepted in engineer -ing.
