Abstract : A general philosophy of the multicriterion approach is presented, and Pareto optima are defined as solutions to the problem. A structural design problem where the weight and some chosen nodal displacements of the structure are taken as design criteria is formulated for hyperstatic trusses and plane frames. The displacement method is applied, and limits for the stresses as well as for the member areas are imposed. Only elastic structures with constitutive and geometrical linearity are considered.
