To determine the internal forces induced by shrinkage in restrained elements or structures whose free shrinkage in the unrestrained state is known, it is necessary to take into account the creep properties and their dependence on age of concrete. The problem leads to an integral equation which has been solved by computer for various typical values of material characteristics. Graphs were then constructed from which the effect of shrinkage can be determined.
