The flexural behavior of reinforced concrete composite beams composed of pre-cast units in which cracks appeared due to construction loading was investigated, and a precise stress analysis method for such a composite beam's section was proposed. Two experiments using eight specimens were conducted considering three parameters: construction load level on pre-cast unit, depth of pre-cast unit and prestress on pre-cast unit. The flexural stiffness of composite beams with cracked pre-cast units was shown to be obviously higher than that of beams which were not loaded at the construction stage, and the average initial crack widths of the former were smaller than those of the latter. The results calculated by the recommended analytical method corresponded closely with the measured values
