Describes a shell arranged as a smooth conoidal canopy, cantilevered 16 ft on both sides and supported on stone walls at the ends of its curved directrix. The general dimens are 20 x 40 ft, with a thickness varying from 1 1/4 to 4 3/4 in. Although the rigorous stress analysis of such a surface would be complicated, its relatively small size and curvature permits an appropriate investigation which amounts to substitution of two straight lines converging at the arch apex for the curved directrix.
