Abstract:
An ultimate laod theory for thin-shell roofs, developed independently by A. L. L. Baker and K. W. Johansen, is presented with modifications as applicable to the design of long, simply-supported, cylindrical shells. The basis of analysis is similar to a rupture theory by H. Lundgren. In addition to design equations for long cylindrial shells, results from exploratory testsare presented in confirmation of the theory. The theory and equations are intended to supplement, not supplant, existing elastic theory.
