AbstractThe foundation performance of a steel tower silo founded on a concrete circular raft in a deposit of soft clay was monitored in order to determine the applicability of standard engineering foundation methods to this type of structure. The allowable bearing capacity of the soil determined from field vane shear tests was more than adequate for the satisfactory performance of the foundation. The measured settlement of the silo was about one third of that predicted. The settlement gauges showed that the maximum soil compression occurred immediately below the foundation although the soil was highly overconsolidated by desiccation. Because frost action occurred, the need to design for frost protection when silo footings extend beyond the silo wall at a shallow depth is discussed.
