Interpretation Number: 1 Topic: Bus End Conditions Relevant Clause: 12.1
Interpretation Request #1
When a pipe bus conductor passes through a bus support fitting, but is not welded to the fitting (i.e., a”slip fitting”), does IEEE Std 605-2008 consider this to be a pinned, non-moment resisting condition or afixed,moment resisting condition?
Interpretation Response #1IEEE Std 605-2008 defines a pinned end as free to rotate and fixed end is defined as not free to rotate.While we recognize that there is not a 100% true pinned or fixed, IEEE Std 605-2008 leaves it to thedesign engineer to determine whether to consider the end condition of the pinned or fixed.
