Live load on areas where cows can congregate?

Live load on areas where cows can congregate?

Live load on areas where cows can congregate?

(OP)
Hello,

I'm wondering about distributed live load in areas where cows can cogregate. Can anybody help me?

Thanx in advance

RE: Live load on areas where cows can congregate?

National Farm Building Code of Canada lists the minimum specified live load for Cattle between 3.5 kPa and 5.0 kPa. Loose housing for cattle is 5.0 kPa. The loading may vary depending on your location.

If tractors need to access the areas to clean stalls or bring hay, higher loads will be required.

RE: Live load on areas where cows can congregate?

5.0 kPa sounds about right, and should accommodate farm tractors as well as cattle.

RE: Live load on areas where cows can congregate?

From AS/NZS 1170.1 (Aust loading code):

dairy cattle, stall area  3.0 kPa
beef cattle               5.0 kPa
farm machinery, normal    7.0 kPa
                heavy     10.0 kPa

And relating that to psf, the numbers are...?

RE: Live load on areas where cows can congregate?

Conversion 4.8 kPa = 100 psf

Also, for Farm Machinery Traffic = 7.0 kPa minimum (There are many combinations of equipment with 10.0 kPa minimum live load). Concentrated live load not less than 23 kN (5,170 lbs) over 750mmx750mm area.

There is also a clause indicating that tractor/equipment live loads shall be increased by 50% in processing and/or loading areas to account for impact or vibrations of the equipment.

I also found this:

Beef Cattle
   Calves to 300 lb. 50psf
   Feeders, breeders 100psf
Dairy Cattle
   Calves to 300 lb. 50psf
   Mature cows 100psf
   Stall area 60psf
   maternity or hospital pen 50psf
Swine
   to 50 lb. 35psf
   200 lb. 50psf
   400 lb. 65psf
   500 lb. 70psf
Sheep
   Feeders 40psf
   Ewes, rams 50psf
Horses 100psf
Turkeys 30psf
Chickens (floor houses) 20psf
Greenhouses 50psf

Thank you anyway for valuable posts

Does that include the appropriate poop factor??

Mike-
Since you opened the gate, so-to-speak, I was going to ask if this was for the secretaries' area?  

RE: Live load on areas where cows can congregate?

That was a low blow.  

Wasn't there a famous horse named Secretariat?
