Load Case for pipe analysis

hi..

i am new user for this caesar II software and have a problem to determined the load case. i.e wind load, seismic load and etc. i don't understand the relation to the result. for example the analysis i already done as below:

1 (HYD) WW+HP
2 (OPE) W+T1+P1
3 (OPE) W+T2+P2
4 (SUS) W+P2
5 (OCC) WIN1
6 (OCC) WIN2
7 (EXP) L7=L2-L4
8 (EXP) L8=L3-L4
9 (OCC) L9=L3+L5
10 (OCC) L10=L3+L6
11 (OCC) L11=L4+L5
12 (OCC) L12=L4+L6


thus, there is comment that L7=L2-L4 is not correct
and for occ code code compliance check i have to combined WIN and SUS.

other than that i need to include seismic and loads U1 and U2 in the case.

the problem is, i don't know how to determined the relation to produce the result.

anyone can help..plssss...

Once you login, you will find search facility at right top corner of the page.

Search for keywords like "Load case", "Load combination" etc

Please find attached the CAESAR II load cases definition. This might be helpful for you.

Shiela,
I think you should only have one set of pressure (i.e. design pressure, P1). Build another operating load case that include occational load (wind or siesmic), then subtract that to the native operating load case for you to get OCCasional load alone, doing that the effect of the other loads will be included.
