摘要
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 history analysis.It is shown that the average result of equivalent linearization method can be accepted in engineering.
