Abstract A proposed calculation model is adopted for the analysis of the composite simple steel-concrete beams with formed steel decking, valid up to collapse, which takes into account the effect of slip at interface between the concrete slab and the steel girder. This model uses relatively sophisticated behaviour laws: non-monotonous variation law of concrete in compression, weak resistance of concrete in tension and especially the phenomenon of strain hardening for steel. As for the stud connectors, they are characterized by variable stiffness in shear. The resolution of the model is made easier in adopting the formulation by transfer matrix method the unknown vector containing some internal forces and generalized displacements. A computer programme is developed to deal with this mathematical model. After checking the efficiency and accuracy of the proposed model and the.computer programme with the available experimental test results a versatile parametric study is performed to investigate the effects of the degree of connection, the goemetrical dimensions of composite section and the type of loading on the overall behaviour of composite beams. |
