This paper contains a critical review of research work in the field of nonlinear finite element (FE) analysis of reinforced concrete (RC) and prestressed concrete (PC) surface structures and of thick-walled RC structures, carried out, in the eighties, at the Institute fot Strength of Materials of the Technical University of Vienna. The title of the paper reflects the author's "mixed experiences" with such analyses of RC and PC structures, gained during the last decade. The expectations were fulfilled insofar as these analyses appeared to be a significant improvement over classical modes of structural analysis of RC and PC structures, which were not able to account adequately for several truly (or seemingly) important mechanical phenomena. The expectations were (fortunately) not fulfilled as far as the anticipated importance of some of these phenomena on the static repsonse of the considered structures was concerned. It was found that, in general, relatively simple constitutive models permit a reasonably good prognosis of the structural behavior of RC and PC structures up to the ultimate load.
