摘要
通过引入连接转动刚度及偏心支撑,导出了偏心支撑半刚接钢框架柱计算长度系数理论公式。采用ANSYS软件对D形偏心支撑半刚接钢框架进行了非线性屈曲分析,得出了偏心支撑半刚接钢框架柱计算长度系数表,并回归了建议计算公式。
The critical factor formulas,which are applicable to eccentrically braced steel frames,were derived by considering relative rotational stiffness of beam-column connections.Finite element models of steel frames with semi-rigid connections were established using ANSYS.Through buckling analysis of eccentrically braced steel frames with semi-rigid connections,the effective length factor of column was derived.The regression equation,which is fit for braced steel frames with semi-rigid connections,was gained.
