A Study in Wall Pressures in a Flat Clear-Span Cottonseed Storage House

M. H. Willcutt


 
ABSTRACT

A study of a clear-span, flat cottonseed storage building was conducted to determine the pressure exerted on the side walls by cottonseed. Pressure in the wall of a scaled emulation chambers were studied to determine whether or not the wall pressure in a cottonseed storage building could be emulated.

Results from these studies indicate that cottonseed exert a pressure on the building as a function of the total depth of the seed. A relationship for wall pressure was established as a function of vertical pressure for the chambers evaluated. The maximum wall pressure in a cottonseed storage building was found to occur at approximately 15 to 20 percent of the total seed depth above the floor. The maximum horizontal pressure observed for the 19 ft eve-height storage building was 285 lb/ft2 and occurred at 4.5 ft in 1994.
