Appendix V - Radial Load Imposed on End Stiffeners

Appendix V - Radial Load Imposed on End Stiffeners

Appendix V - Radial Load Imposed on End Stiffeners

(OP)
In Section V.8.2.3.1 an equation is provided for the radial load imposed on an end stiffener (V1).

Section V.3.1 (Nomenclature) provides the definition of V1 and states the units are (lb/ft).

In the example (Section V.10.2.16), V1 is computed BUT the Code indicates the units are (lb/in).


So, what are the units of V1 when computed as PsH/48 ??

RE: Appendix V - Radial Load Imposed on End Stiffeners

See Example 16 on P. V-20.  There they use that equation and get V1, but V1 is in lb/inches, not lb/ft.  This is consistent with the how Q is handled in V.8.2.2.3.

Assuming that the radial load on the entire shell gets transferred into the end stiffeners would give a value of 24 rather than 48 in that equation, being 1/2 and 12"/ft combined.  I'm not sure where the other 2 factor comes in.  Using shell theory for an unbuckled shell would give a much smaller result.
