This is my doubt.

Imagine a piece of piping with 3 cases of load:

T1= 500º
T2= 25º
T3 = 560º

If I realize the calculation of those 3 cases of load in 3 different files, the verificacion of occasional stress code, IS CORRECT.

But analysing the 3 cases together in the same calculating file, the occasional stress es higher than the 100%.

The reason of that,I believe is due to that the SH of comparison of occasional stress is taken for the higher temperature of the 3 cases.

The case that gives an error ( code compliance ) is T2. But this way, the Sh material should be Sh at 25º, in my opinion.

I wonder : If the Sh considered by the program is the SH maximun for the 3 cases or only Sh for each one of the 3 cases??????


I think CAESAR uses the value Sh for the higher temperature of calculation, that is, 560º, whatever the calculation is. And what I think it should do is to use the Sh in each one of the cases separately.

I beg of you to give me a due in such a matter.

Thanks a lot.
