AbstractIn this study, a nonlinear three dimensional finite element analysis has been used to conduct an analytical investigation on the behavior of curved in plan composite concrete-concrete beam using the analysis system computer program (ANSYS v.9.0 2004). Various types of beams, with available experimental results are chosen to check the validity and the accuracy of the adopted models. In general good agreement is obtained. The maximum percentage difference in ultimate loadcarrying
capacity is 12%. Parametric studies are carried out to study the influence of the curvature (L/R ratio of 0, 0.1, 0.15 and 0.2) on the behavior of the curved in plan composite concrete beams. Also, some important material and solution parameters that affect the structure behavior are studied. These include the slab thickness, support condition, compressive strength of concrete and the percentage
of steel across the interface between the stem and the slab of the composite beam.
