    Description of Concrete Creep Based on Microprestress-solidification Theory

  • Original language description

    Creep of concrete is strongly affected by the evolution of pore humidity and temperature, which in turn depend on the environmental conditions and on the size and shape of the concrete member. Current codes of practice take that into account only approximately, in a very simplified way. More realistic description can be achieved by advanced models, such as model B3 and its improved version that uses the concept of microprestress. The value of microprestress is influenced not only by the evolution of pore humidity but also of temperature. In this contribution, values of parameters used by the microprestress-solidification theory are recommended and their influence on the compliance and stress distribution is evaluated.
