Abstract:
In the first part of the present paper, the so-called Improved Dischinger Method, developed by the author, is identified as belonging to a class of methods which reflects the mechanical behavior of concrete in a reliable way, consistent with the assumption of linear viscoelasticity. At the same time, the basis of some other well-known methods is evaluated. In the second part of the paper, the class of methods mentioned above is evaluated with respect to practical applicability. Among other things, two features are hereby demonstrated which are much appreciated in practice, and which do not apply to any method: (1) The user has the choice of handling his problem on the basis of one of three consistent, analytically-determined alternative formulations of the stress strain relation; (2) Standard solutions may be developed which apply to any concrete. Finally, it is demonstrated how the Improved Dischinger Method may be used in "hand design" of concrete structures.
