Abstract:In order to get the carrying capacity,distribution and growth of crack as well as the deformation of simple prestressed H-steel reinforced concrete beam,5 specimens were designed,manufactured and tested in this paper. Relative data were obtained and analyzed. The calculation formulas of carrying capacity,crack width and stiffness for the beam were presented based on the analysis of these data.
Keywords:prestressed concrete  H-steel  composite beam  load-carrying capacity  width of crack
