The main purpose of the present paper is to investigate the effect of several important parameters on the behavior of external prestressed composite steel-concrete beams. ANSYS computer program (version 12.0) has been used to analyze the three dimensional model. The nonlinear material and geometrical analysis based on Incremental-Iterative load method, is adopted. These parameters include effect of compressive strength of concrete, effective prestressing stress to ultimate stress ratio, effective height to center of prestressing cables ,effect of external prestressing technique , type of loading, tendon profile, degree of interaction , ratio of thickness to width of concrete slab , using unsymmetrical I-steel beams ,effect of number of stiffeners and effect Full and Partial Interaction.<\/p>\n
