摘　　要：对圆钢管销铰连接中端板的力学性能进行了研究。建立了端板的简化力学模型,对端板的受力机理进行了探讨。建立了便于使用的端板承载力计算公式,根据建立的100个有限单元参数模型的线弹性计算结果,给出了计算公式中各系数的计算表格,给出了表格的使用方法和算例。最后对计算表格的有效性进行了评价,并得出一些对此类节点设计有参考价值的结论。Ultimate capacity of unstiffened cover-slab of tubular structure using in the supporting joint is researched. The mechanical principle of the unstiffened cover-slab is discussed, and the mechanical models are established. Based on the model, the formulas of bearing capacity are recommended. According to the results of finite element analysis of 100 models which vary with the geometrical parameters, two handy tables of the factors in the bearing capacity formulas are established. And the applying method of the tables is given by an example. Finally the evaluation on validity of the tables is given, and some valuable conclusions are drawn from the tables,
