Silo Foundation According to the Modulus of Compressibility Method

Column foundation and soil layers
Column foundation and soil layers

The use of the modulus of compressibility method for slab calculations is illustrated based on the example of a silo surface foundation. The four silo cells transmit their loads via nine columns to the 0.8-m-thick square foundation slab that rests on the layered subsoil.
