Whilst the advantages of iterative continuum-based optimality criteria (COC) methods in cross-section optimization ('sizing') were discussed elsewhere, this paper is devoted to applications of the above technique in layout optimization. Earlier studies of the latter field by others used a two-stage process consisting of separate topological and geometrical optimization and considered only a very small number of members . It will be shown here that the COC algorithm achieves a simultaneous optimization of the topology and geometry in layout problems with many thousand potential members. Moreover, some observations on shape optimization by the 'homogenization' method are offered and an alternative approach to global shape optimization is suggested.
