Hi
I would like to here of other peoples' experience on the use of PED design stresses , ESR 7.1.2.
At present I use these stresses and the required joint coefficients only for shell internal pressure calculations, as these are the only general membrane stresses. For local load,external pressure, flat end, saddle and nozzle reinforcement (away from seams) etc. I use those design stresses from the particular design standard specified - mainly PD 5500.
Recently a colleague has told me that HSB insist on the use the ESR stress for all calculations but I can see no justification for this restriction.
This seems a fundamental area and any comments are greatly appreciated
