A practical method is developed for sequential generation of optimal circular cylindrical trusses for frequency ranges. In this method, all the optimum designs are swept out with respect to the prescribed fundamental eigenvalue. This method is shown to be effective also for a range of repeated fundamental eigenvalue. The radius of curvature of the circular cylindrical truss is adopted as a subparameter, and the optimal trusses are generated parametrically for a variety of different radii of curvature. The effectiveness of the proposed method is demonstrated for a 504-bar circular cylindrical truss, and the characteristics of the optimal sets are investigated. The existence of the optimal radius of curvature is demonstrated through the example of a 200-bar circular cylindrical truss.
