Lateral file loads

Lateral file loads

Lateral file loads

(OP)

It is reasonable to reduce the live load of the area occupied by the file and consider the net load as a concentrate load in a steel joist capacity check on new loads.

Example:

Lets say the the base area of a file is 42" x 18" = 5.25 square feet

Live load requirement 50 psf

50 psf x 5.25 sf = 262.5 pounds

The lateral file + content = 785 pounds

The net concentrated load to be considered in an analysis is 785 - 262.5 = 522.5 pounds the will be considered as a concentrated load.

RE: Lateral file loads

I would not include the distributed live load concurrently with the file load. Ignore the distributed load over the file area and use the actual file load where it's actually going to load the joist. I usually use either 125 or 150 psf for lateral files, depending on how much storage space is available.

RE: Lateral file loads

Your approach is fine. The file is a form of live load so adding the distributed load would be double counting it.
