摘　　要：型钢混凝土异形柱结构是指在钢筋混凝土异形柱截面中配置型钢的结构。它结合了钢筋混凝土异形柱结构和型钢混凝土结构的优点,具有广阔的应用前景。本文利用ABAQUS软件对型钢混凝土异形柱框架角节点在纯扭荷载作用下的情况进行了有限元模拟分析。分析结果表明,型钢对于节点的抗扭承载力的提高作用明显。根据叠加方法并通过引入考虑组合作用的节点抗扭承载力影响系数对型钢混凝土异形柱框架角节点建立了抗扭承载力计算公式。The steel reinforced concrete special-shaped column structure is the structure that steel layout in the cross-section of reinforced concrete special-shaped column structure.It combines advantages of the reinforced concrete special-shaped column structure and the steel reinforced concrete structure.The steel reinforced concrete special-shaped beam-column corner joints under torsion were analyzed by using the software ABAQUS.It is shown that the results analyzed are consistent with actual situation.The steel enhance the torsion capacity of joints dramatically.The torsion capacity formulas of steel reinforced concrete special-shaped beam-column corner joint were presented by followed and introduced the coefficient of torsion.
