heal.abstract	The generality of a recently developed 'constant parameter' three-dimensional finite-element model for structural concrete, based on a brittle constitutive relationship at the material level, is now extended to prestressed concrete members. The adopted technique of applying the prestressing force as a constant load at the first load step of the non-linear analysis, and removing from the input that part of the steel tendon stress-strain curve which is effectively utilized in the prestressing operation, although somewhat simplistic, is found to be adequate for practical purposes. What emerges from the present Paper is that the existing finite-element package, applied in the past to plain and/or reinforced concrete members made from a wide range of concrete strengths, is equally capable of catering for prestressed concrete structural forms. As well as serving as a tool for analysis, the numerical model also provides insight into design itself by identifying the path of the compressive forces within a structure.	en
