| 摘 要： | 针对钢-混凝土组合框架的特点，利用考虑滑移影响的组合梁等效刚度计算方法，考虑组合楼盖的组合效应、组合梁与柱的实际约束程度以及节点的半刚性连接特征等因素，推导出有侧移和无侧移半刚性组合框架柱组合梁的刚度修正系数，提出了有侧移及无侧移组合框架柱的稳定设计方法。算例分析结果表明，该设计方法有效地利用了组合效应和节点的延性，具有较好的经济效益。

| Abstract: | According to the characteristics of steel-concrete composite frames, the composite effect of floor slab, real constraint degree between composite beams and columns as well as features of semi-rigid connection of joints were considered by using the calculation methods for equivalent stiffness of composite beams under the slip effect. The stiffness modified coefficients of composite beams of sway and non-sway semi-rigid composite frame columns were established and the stability design methods of sway and non-sway composite frame columns were put forward. Example analytical results show that the design method effectively makes use of composite effect and ductility of nodes, and has rather good economic benefits. |
