Abstract
In this paper it is discussed how to choose and use a linear creep function to analyze the creep of concrete. Certain boundary conditions for a creep function are presented. With the help of an aging Kelvin-Voigt model, the physical significance of the boundary conditions can be proved. According to the principle of superposition, two integral types of the constitutive law are compared, and the generally correct form is pointed out, which is necessary to compute creep under influences of time-dependent variables such as temperature and humidity.
