摘　　要：为探讨组合桁架的有效计算方法可将组合桁架视作桁架体系，利用有限元方法精确计算。在划分单元和推导单元刚度矩阵时，关键是连接件，个按其两大功能特征作为独立的特殊单元处理，结果是成功的。For discussing the effective calculating method for composite truss,the composite truss can be regard as truss system and calculated accurately usirg finite element method. During dividing elements and deriving unit stiff matrix,the key is the connector, Dealing with the connector as independent special element according to its two main fumction,function,a successful result can be obtained.
