摘　　要：钢管混凝土组合框架在实际工程设计中缺乏正弯矩作用下端板连接钢管混凝土组合节点计算简化模型,本文根据组合节点可能的失效模式,考虑了端板类型、楼板组合作用、柱截面类型、荷载类型的影响,建立了平齐或外伸端板连接钢管混凝土组合节点在对称荷载或非对称荷载作用下的力学模型。In the actual engineering design,CFST composite frames lack a simplified calculation model for connecting steel tubular composite joints with end-plates under positive bending moment. This paper considers the effect of the type of end plate,the function of floor combination,the type of column cross-section,the possible failure modes of composite joints and the type of load,and establishes a mechanical model for the joints of CFST composite joint with flush or extended end-plate connections under symmetric or asymmetric loading.
