On the Stability of Rectangular Plates Reinforced by Stiffeners and Subjected to Bending and Shearing

摘要

The report deals with the problem of stability in the elastic region of rectangular, thin slabs which are strengthened with horizontal and vertical stiffeners and stressed simultaneous by bending, compression and shear. The investigation was based on the differential equation of the elastic surface. In this way, insofar as shape and stresses are concerned, a more general treatment of the problem was possible. As an application, two special cases were treated: a slab reinforced in accordance with practical ideas subjected to pure bending, as well as to bending and shear, the critical values of the stresses being given in tabular form in dependence on the stiffenings.
