摘要
对框架柱的计算长度系数法和二阶分析设计法详细列出设计公式进行了比较,详细解释了内力采用二阶分析时计算长度系数取110的原因。通过算例分析,对两种分析设计方法进行了定量比较。对框架的比较表明,纯框架如果采用二阶分析方法设计,无需计算稳定性。
A detailed comparison bet ween effective length approach and second order analysis design appro ach of column in frame is carried out by listing respective formulas ,and the reason why effective leng th factor is taken as 1 0 when sec ond order analysis is adopted is c learly explained Then two examples are presented to illuminate the qu antitative difference between the two design approaches of column in frame and indicate that the in pla ne stability of unbraced frame nee d not be evaluated if second order analysis design approach is used
