Summary

This paper deals with an enumeration method of various optimal truss topologies which have the same objective value. In this paper, the truss topology optimization problem (TTOP) is formulated as a multiobjective optimization problem (MOP), which is to find the cross-sectional area of truss members such that both the structural volume and the compliance are minimized. This MOP can be transformed into an equivalent linear programming (LP) problem and the optimal truss topology can be obtained by the interior point method. Using this optimal solution by the interior point method, other various optimal truss topologies with the same objective value can be systematically enumerated. The applications of the proposed method are illustrated in numerical examples with a discussion of the characteristics of the design results.
