It presented a practical approach for calculating the approximate second-order elastic moment of the partially-braced frame column,based on the present design code of steel structures and the approximate magnification factor of second-order moment of unbraced frame column.
在现行钢结构设计规范的基础上,结合无支撑纯框架柱二阶近似弹性分析的二阶弯矩放大系数,提出了用于弱支撑框架柱考虑侧移效应的二阶近似弯矩放大系数实用公式。
