Uniaxial Behavior of Concrete in Cyclic Tension

Abstract

A new one‐dimensional model for random cyclic tension in concrete is developed. The model determines several geometrical loci, defined as focal points, in the uniaxial stress‐displacement plane, which are used to compute the complete unloading‐reloading curves. Given the complete load‐displacement curve, the focal points are located, and the path of any unloading‐reloading cycle can be computed. A cycle may also be plotted graphically without further calculations. The model is compared with test results recently obtained at the Stevin Laboratory, Delft University of Technology, as well as with other available data, and good agreement is shown.
