Dear. all

I have infromation about snow load but I couldn't input the
Caesar program. coz I'am not sure.

formula:
s = s0μ
Where:
s is the value of snow load on the horizontal projection (kN/m2)
s0 is the characteristic value of snow load on the ground =0,7 (kN/m2)
μ is the snow load shape coefficient = 0,4

When I input Uniform load, How can i change kn/m2 -> kgf/mm
and Do i consider pipe diamater? i think we already input the
all pipe information. so, i think just need typical snow load and caesar2 automatically calculate(F/L).

Take your load in KN/m2 and multiply by the pipe diameter, which will give you the uniform load in KN/m. That is the input needed for CAESAR II.

Thanks for your quick response.
but I 'am still confusing....
Please give me a Example.

Sorry, I missed the weight conversion. You can look up the conversion from KN to KGF, it's about 101.97. Just write it out with units and you can obtain the unit load in KGF/M.
Once you have that, then convert from M to mm.
