Abstract: For application of FRC in structural members it is necessary to ensure not only appropriate technology for production, but also adequate methodology for design. For structural analysis constitutive models of FRC are needed. Submitted paper is directed to some aspects of material properties determination on the basis of laboratory testing.
The task is to obtain stress-strain diagram of FRC, when relationship between load and deflections is known from four-point bending test on a prism. One type of such a procedure (called inverse analysis) is described and results of inverse analysis are used in structural analysis by FEM to compare the results to tests. Effects of shear on deflections and consequences for determination of material parameters are also discussed.
