If this is done, then the calculation of stress is merely incidental. Click on image to enlarge. The photograph of another shell by Candela shows a dome made from three hyperbolic paraboloidal units separated by skylights. The curvature of the hypars is not as great as the previous example so he was more conservative. Note the steel columns under the edges.
Deflections are a constant problem with so thin members.
