Abstract The theoretical basis for a new optimality criteria method (DCOC) was presented in Part I of this study (Zhou and Rozvany 1992). It was shown in that paper that a considerable gain in efficiency can be achieved by the proposed method, since the Lagrangian multipliers associated with stress constraints can be, in general, evaluated explicitly and hence the size of the dualtype problem is greatly reduced. The superior efficiency of the proposed method, for problems involving a large number of active stress constraints, was also demonstrated through simple numerical examples. In Part II, the computational algorithm of DCOC is presented in detail and several standard test examples are used for verifying the correctness and efficiency of the proposed method.
