Calculation on Plastic Internal Force of Reinforced Concrete Member under Axial Force
The design of reinforced concrete structure often used the elastic internal force as the design basis, but the nonlinear behavior of reinforced concrete structures brings about errors in calculation of statically indeterminate structure. By considering the nonlinear properties, the mechanical responses of reinforced concrete structure were investigated, on which an axial force loaded at their middle span section. In a series of analysis on internal force of the reinforced concrete member at all loading stages, through the deformation compatibility equation and the balance equation, the formulas for calculating elastic-plastic internal forces and strains were derived. Comparative examples are provided and the results show a large error between internal forces calculated by the structural mechanics method and those by the elastic-plastic method proposed in this paper, and the maximum error is about 8 times.
