摘要
通过一定的等效原则 ,将结构的二阶效应转化为结构的负刚度 ,并通过合成法将框架 -支撑体系等效为一根剪切型悬臂柱和弯曲型悬臂柱的并联等效模型。使用该等效刚度并联模型只需按一阶方法分析可得二阶分析结果 ,避免了常规方法的反复迭代 ,计算速度快 ,所需机时少 。
In this paper,according to equivalent principle,Second order effect of structures is transformed into negative stiffness,and a braced frame system is equivalent to the model of bending\|shear formes through compound method.With the model iteration can be avoided,its calculation velocity is quick,calculation time is little,and calculation precision can meet the demands for practical design.
