Dear

Can any one explain me how to input snowload & earthquake load both in Uniform loads column. As i have inputed the earthquake load as value of GX,GY & GZ and now want to input the snowload on pipe...?

Thanks

At the present time, uniform loads have to be all of the same "type". Either all "force / lenth", or all "g's". You cannot mix the two types in the same input file.

You can enter the snow load over a section of piping by increasing the density of th insulation over the section of piping that will see the snow load

Yes that can Mr. Khan do.
But he mixed then the normal isulation loads (weight load case) with a occasiunally load (snow load).
I think this will be to much for the sustained stress equation.

Another option would be to split the distributed load into a set of discrete loads.

This can be burdensome if you have extended lengths of pipe.

I think not so.
Example :
Its a deflection/stress difference if have a beam between two restraints
onetime with a uniformload and one time with two forces on the nodes.
In the second case only the restaints get reaction forces without deflection the beam.

snow load can be used as sustain load by density change .... considering there should not be too much difference

I disagree Ohliger

I believe a snow load should be considered a sustained load.

It is a dead lead rather than an occasional load. You can have snow for a significant part of the year (or all year depending where you are).

Occasional loads are exactly that - they occur occasionally - wind, seismic, rupture disc disharge loads etc.

Its a question of the location and load time.
Snow load :
Florida ==> occasional
Alaska ==> sustained

Then its only a question of load time, if occasional or sustained.
If you have a location with (example 200 days wind) then its a sustained load and not ocassional load.

Dear All,
It's an interested subject.
Today I have a piping model with many load case to check, seismic, snow , settlement and I 'm lost , I cannot define my load cases and combination for all those load, and how I can imput the snow and seismic as uniform load together , or I have to define the snow as force?
For the settlement , this is my first time to do it, I have 25 mm for tank, what are the nodes that I have to enter this displacement? only node connected to tank or what?
I need your help please.
Best Regards
