This paper presents a new concept for efficient treatment of the large number of constraints that arise in finite dimensional structural optimization. Constraints are imposed on stresses and displacements, which must hold at all points of the structure. The method replaces these pointwise stress and displacement constraints with a set of integral constraints. This redefinition is based on interpreting stress and displacement constraints from a global (structural) rather than a local (element) point of view.
