In Part I of this study, a general theory of optimal layout for long-span truss-grids was outlined, and then it was applied to circular simply supported truss-grids whose span length does not exceed a certain limiting value. The optimal solution for the above problem was shown to consist of a purely circumferential moment field. It is established in Part II that for simply supported circular truss-grids of longer spans, the optimal solution takes on a more complicated topography consisting of both circumferential and radial moment fields. In addition, optimal solutions are presented for circular truss-grids that are built-in (clamped) along their edge. Finally, a weight comparison for various types of solutions is given.
