... are determined by tests. The shape of the compression-stress distribution and the position of its centre of gravity are denoted by symbols for which safe limiting values are obtained experimentally. A plastic theory for the ultimate longitudinal bending strength of cylindrical shells is also presented...

...W T MARSHALL Synopsis. The membrane theory for the stresses in thin shells is based on the fundamental assumption that there is no change of shape of the shell on loading. In shell-roof construction, however, there must be a deflexion of the edge tie-beam, with resultant secondary stresses...
