根据框架柱计算长度理论,通过引入梁削弱式节点参数特性,建立了四跨三层的梁削弱式节点连接的侧移钢框架数值模型.利用ANSYS软件对梁削弱式节点连接的侧移钢框架数值模型进行了非线性屈曲分析,得到了梁削弱式节点连接的侧移钢框架柱计算长度系数.结果显示,梁削弱式节点侧移钢框架柱计算长度系数较常规节点增加1.5%～12.9%.最后,经过回归得到了梁削弱式节点连接的侧移钢框架柱计算长度系数建议公式.

According to the column-effective length theory of steel frames stability design,and by considering the characters of dog-bone connections,and finite element models of four-span three-story sway steel frames with dog-bone connections were established using ANSYS program. Through nonlinear bucking analysis of sway steel frames with dog-bone connections, the effective length factors of sway steel frames were derived. Simulation results showed that the effective length factor of sway steel frames with dog-bone connections increased within the range of 1.5% to 13 % in comparison with that of sway steel frames with conventional connections. The suggested formula, which was fit for sway steel frames with dog-bone connections, was gained by regression analysis.
