Modelling Time Dependent Deformations in Reinforced Concrete Flexural Members
Most methods which have been developed for calculation of the time dependent deformation of reinforced concrete beams and slabs are directed towards prediction of final values for design purposes. Where the analysis of the interaction of contiguous members of differing ages is to be done (e.g. progressive bridge construction), a method that can give periodic prediction is needed. The paper describes a method of this type. The reinforced concrete section is treated as a set of elements with the stress and strain history of each being progressively calculated and recorded for the separate but concurrent actions of shrinkage and bending. These are incremental shrinkage strains, with their simultaneous relaxation and stress adjustments, and bending stresses and strains which have similar adjustments.
