Grain storage structure

Abstract

A grain storage structure including a circular upstanding support wall with an upstanding support tower being centrally positioned within the support wall. A plurality of curved and spaced-apart first roof trusses have their lower ends secured to the upper end of the support wall and have their upper ends secured to the upper end of the support tower. A plurality of curved and spaced-apart second roof trusses having their lower ends secured to the upper end of the support wall between adjacent first roof trusses. The upper ends of the second roof trusses are connected to the first roof trusses below the upper ends thereof. A second embodiment of the storage structure is disclosed which has an oblong shape when viewed in a top view.
