VERIFICATION OF THE CALCULATION MODEL FOR DETERMINING THE INTRINSIC DEFORMATIONS OF STRAINING CONCRETE WITH DISPERSED REINFORCEMENT

Abstract

Most of the approaches for determining the properties of self-stressing concretes are based on experimental selections of mixes followed by control of basic characteristics.
In this paper it’s proposed to switch to analytical modelling as the most universal tool allowing to minimize empirical investigations. The modified strains development model (MSDM) of self-stressing concrete under conditions of spatial restriction of free strains by dispersed reinforcing elements of arbitrary stiffness allows to determine proper deformations in arbitrary time interval up to the moment of free expansion stabilization.
