This paper deals with a special class of minimum weight design problem invo
lving discretized structures, holonomic (reversible) plasticity, and constr
aints on displacements. A key feature of the optimization problem is the pr
esence of complementarity conditions, involving the orthogonality of two si
gn-constrained vectors. This problem falls within the important class of so
-called Mathematical Programs with Equilibrium Constraints (MPECs). Two sim
ple algorithms are proposed to solve our synthesis problem and application
is illustrated by some examples concerning truss-like structures. (C) 1999
