The previous paper shows that a preserved compressive stress in concrete composite beam due to pre-stressing works as the same as an axial resistant stress occurred by steel bars and PC tendons, and the works of preserved stresses depend oh levels of pre-stressing force ratio. In this paper, a proposition for design of concrete composite beam that is accurately required cross-section stresses is shown on a way based by this theoretical method. And an optimal design for balanced-design between a beam performance and its cost behavior is proposed by using the property of the preserved compressive stress. Both of performance and cost of a concrete composite beam comply mainly with its reinforcements, steel bars and PC tendons in a certain condition, and choosing among their combinated reinforcements should be very important for balanced-design of performance and cost. It will be very effective to use their cost behavior of reinforcements for cost saving.
