    Abstract

    ![CDATA[Cracking of the concrete slab in the hogging moment region decreases the global stiffness of composite steel-concrete structures, also reduces the effect of continuity and makes the structural behaviour highly nonlinear even for low stress levels. In this paper, a nonlinear analysis model using a mixed finite element formulation is presented to predict the behaviour of continuous composite beams with discrete partial shear connection in the hogging moment regions. The tension stiffening effects are introduced in the analysis by using a concrete constitutive model proposed in the CEB-FIP Model Code 1990 which incorporates steel reinforcement. Comparisons between the numerical analyses and experimental results existing in literature were undertaken to validate the accuracy of the model.]]
