.... The Author has attempted to avoid the use of complex mathematical methods by assuming that all bending strains have linear distribution. The neutral axis of members subject to bending is located by the ultimate strains at the extremities of the section for non-sustained load, and safe limiting values...

..., and from differential heating. The loading on anchor-blocks and buttress-blocks ia considered. Formulae are given for the spacing of ring-supports necessary to keep the combined stresses due to bending, eccentricities in alignment, temperature changes, and fluid pressure, within safe limits when judged...
