A short review of rheological phenomenon of concrete creep have been done. There are given the basic integral equation of creep of concrete and derived from it algebraic equations. The limit between linear and nonlinear creep is formulated. An example for nonlinear creep coefficient ?k is given according to BDS EN1992-1-1 and estimated by new proposed formula. Another example is given for analysis of stress and strain state of reinforced concrete section with nonlinear creep according to BDS EN1992-1-1 and according to proposed formula.
