摘　　要： 利用钢与混凝土的材料特性而形成的组合梁,按弹性理论计算的基本假定,均匀连接的组合梁,在端部无特殊约束的情况下,因钢与混凝土的相对温度引起的伸缩,会产生结合面间的相对滑移和连接件的温度应力,本文构造了钢·混凝土结合梁考虑滑移的七自由度单元,利用有限元法和解析法对外荷载和温差作用进行了计算,并将计算结果加以对比。 When there is no special restraint at the end of the combinating beam formed with the material characteristics of steel and concrete, the relative slippage between the interfaces and the temperature stress of connect pieces will bring because of the expansion caused by the relative temperature of steel and concrete and according to the basic hypothesis calculated by the elasticity theory. This paper poses the seven-degree freedom unit used for steel-concrete combinating beam considering slippage and utilizes the finite element method and analysis method to calculate the action of the external load and temparature difference, and also compares the calculating results.
