    Abstract
  • Considering the effect of shrinkage and creeping with the average shrinkage strain, and by aid of the curvature parameter k, this paper analyzes the mechanical characteristic of reinforced concrete section.Then a formula that can describe the relation of M and k is derived.According to the section stiffness of the RC beams, this paper gives the formulas to calculate the deflection of the beam at different stage.
