A Symmetrically Loaded Base Slab on an Elastic Foundation

In the design of a base slab it is common practice to assume the reaction distribution and compute bending moments by statics, or by elastic theory if the slab is part of an indeterminate frame. In the latter type of case, fixed-end moments and stiffness values are computed as for an ordinary beam or slab with fixed lo a d distribution. The object of this paper is to develop a method of analysis which takes account of the effect of the rigidity of the foundation upon the reaction distribution. The base slab extends between two vertical walls to which it is rigidly connected.
