Thanks Sam;

But the problem is the given values for the boiler side seems to be as results of an analysis rather than being allowables. There are three different cases and for both the forces moments and displacements are given. I could not understand how such an analysis is done but I cant understand in such a complex piping like boiler how anyone can calculate the allowables either. Is it possible to cut any model and try if it is OK with the limit values?
