DEFORMATIONS OF
CONCRETE
L. Dvorkin and O.Dvorkin
Deformations of concrete arise up at hardening, exploitation and test of
concrete.
Two kinds of deformations of concrete are:
1. Deformations due to applied external loads (power deformations);
2. Deformations due to volume changes under influencing of changes in
temperature and moisture content (own deformations).
5.1. Concrete deformations at short-term load
Concrete Performance in constructions is determined by elastic and plastic
deformations.
Complete deformation of concrete at a definite age of hardening (ετ) is
calculated by the equation:
ε = ε + ε + ε
