FUZZY OPTIMUM DESIGN OF THE PRE-STRESSED CONCRETE BEAM WITH LARGE OPENINGS

This paper is concerned with the optimization of the pre-stressed concrete beams with large openings. An optimum model is set up in which the restraints of the model are dealt with the fuzzy theory. The local optimum solutions for different restraints are discussed. The method of fuzzy comprehensive evaluation is adopted in the search of the optimum solutions.
