Restrained Imposed Deformations Versus Loads

Prof.Ir. Dr.Ing.E.h. Dr.Ir.h.c. Bruggeling, A. S. G.

Summary This paper critisizes the, in practice, generally applied method of the calculation of the effect of restrained imposed deformations on the structural behaviour. In practice these deformations are “translated” into loads. This approach is supported by Eurocode No. 2 “Basis of design” articles 2.2.2 and 2.3.3. This approach must be regarded as wrong. To prove this statement a tension member is subjected to a load in combination with a restrained imposed deformation. In the first part an engineering model of a tension member in structural concrete, in this case without artificial loading by prestressing, is presented. In the second part a method is proposed to calculate the combined effect of external load and imposed deformation.
