The Differential Equation According to Dischinger

The differential equation solved by Dischinger in 1937 [l] describes the redistribution of action effects and/or stresses developing in a structure as the result of creep and shrinkage, if purely elastic structural members interact with others subject to creep. The coupling of these members can be local (e.g., a concrete arch with a steel tie or unbonded prestressing) or continuous (e.g., reinforced concrete, prestressing with bond, composite girders). Since the use of the equation is not limited to concrete construction, we use the subscripts e for the elastic element (e.g., reinforcement or prestressing steel); and c for the member which is subjected to creep.
