Numerical Analysis of Rectangular Rafts on Layered Foundations

The behaviour of perfectly smooth, uniformly loaded rectangular rafts of any rigidity resting on a homogeneous elastic layer which is underlain by a rough rigid base is analysed. Graphical solutions are presented which enable the determination of vertical displacement at the centre, mid-edges and corner of the raft, and the maximum bending moment in the raft. This paper helps to understand the numerical analysis of rectangular rafts.
