Description: As more and more large tower silos are built on supporting soils of undetermined bearing capacities, the number of cases of settled, leaning and overturned silos in Canada continues to increase. A previous paper (Bozozuk 1974) dealt with factors which determine the safe allowable bearing pressures of clay soils under tower silo foundations. This paper deals with a design procedure for silo foundations capable of spreading the load of a single silo plus contents over sufficient soil area for safe support. A tower silo can easily overload the area of soil directly under the silo cylinder and floor. Then it is necessary to spread the weight of the silo and contents over a bearing area considerably greater than the base of the silo cylinder. The reinforced extended ring foundation described here is a method of increasing the foundation bearing area beyond the wall of the silo cylinder without wasting unnecessary foundation concrete and reinforcing steel under the silo floor.

Keywords: reinforced extended ring foundations for top-unloading concrete tower silos
