Optimal archgrids: a variational setting Print
R. Czubacki, T. LewiƄski, Optimal archgrids: a variational setting, Structural and Multidisciplinary Optimization 2020,

The paper deals with the variational setting of the optimal archgrid construction. The archgrids, discovered by William Prager and George Rozvany in 1970s, are viewed here as tension-free and bending-free, uniformly stressed grid-shells forming vaults unevenly supported along the closed contour of the basis domain. The optimal archgrids are characterized by the least volume. (...)
