Re: Liberal Allowable Stress

Dear Friends,

Don't divert the topic to Saddam and US etc etc. It's a pity of our group that many times such diversions take place in spite of reminders from the moderator.
If anybody do not want to answer, don't but do not divert the discussions to such internationally hot topics.

Liberal Allowable Stress: (Reference: Caesar II Tech. material)

A conservative formulation of the allowable expansion stress range for many codes in CAESAR II is calculated from: f ( 1.25 Sc + .25 Sh )
When the user requests that the "Liberal Allowable" be used, the difference between Sh and Sl, provided Sh > Sl, will be added to the term inside the parenthesis, i.e.
SA(Liberal) = f[ 1.25 Sc + .25 Sh + ( Sh - Sl) ] The liberal expression will only be employed when there is at least one sustained stress case in the load set. If there is more than one sustained stress case in a single problem, then the largest of Sl, considering all of the sustained cases, for any single element end will be chosen to subtract from Sh. Because the sustained stress varies from one pipe to another, the allowable expansion stress will also vary.

With best regards.
