Dear Friends,

Does the load & Displacement vary with respect to the design code BS 7159 and ASME B31.3? I have verified this in CAESAR II with codes ASME B31.1, ASME B31.3 & ASME B 31.4 and I observed very slight difference in the results.

Obviously based on the displacement and force formula the results are same irrespective of the design codes. As the code Stress formula is different for each design code, does this have any impact in loads & displacement? Kindly enlighten me in this regard.
