Hi all,
I am facing troubles using "max combination method" in load case definition.
In the results i have, the max load case gives results that are different from those appearing in the equations i selected previously.
As my english is far from correct, i'll give you an example:

i defined L49=L4,L15,L16,L17,L18 (OPE) using max comb method.

here is an extract of the restraint summary report:
4(OPE) 3512 -11049 1441
15(OPE) 3385 -11189 -171
16(OPE) 3407 -10894 1329
17(OPE) 3165 -10216 729
18(OPE) 3604 -11829 404
49(OPE) 3815 -12061 1441

i don't understand why X and Y values in Case 49 are such values !
Z value seems correct.
Most of my other max cases give logical results, not this one.
Could anyone help me ? Thanks

Do not try to summarize "Summary Reports - it won't work.

The restraint summary sums all the loads for each DOF at a particular node (you could have several if there are several restraints at the node). The resulting sum is what you see in the restraint summary report.

If you perform a Max of several load cases, and then ask for a restraint summary, your summing the maximums across more than one load case, so you could end up with a larger, ficticious maximum.

If you want a Max Summary Restraint Report, then use your case 49 (as above), but request the standard Restraint Report, not the Restraint Summary.

Thank you Richard for your quick and detailed answer.

It is now perfectly clear for me.

Regards,
