Title: The Mechanics Of Plastic Flow Of Concrete
Author(s): J. R. Shank
Publication: Journal Proceedings
Appears on pages(s): 149-180
Abstract:A parabolic type of equation is found to closely express the time-deformation curve for plastic flow. Test data available are summarized and tabulated giving the coefficients and exponents for the curves. These data are studied and quantitative values are given affect plastic flow. to express the conditions that on this are developed exact expressions for reinforced concrete column stresses after a certain period for sustained load and also for sustained strain. Approximate procedures are given for beams. Some space is given to similar expressions for shrinkage.
