Abstract
This work presents the Two-phase method for fuzzy optimization of structures. In the first phase the fuzzy solution is obtained by using the Level Cuts Method and in the second phase the crisp solution, which maximizes the membership function of fuzzy decision-making, is found by using the Bound Search Method. Illustrative numerical examples involving skeletal structures and reinforced concrete slabs are solved.
