ROARKS table 11.4
ROARKS table 11.4
(OP)
I have a question about the a/b ratio in table 11.4 of Roarks Formulas 7th edition.
I want to use Table 11.4, Case 8d for an decreasing load along the height but my a/b ratio is more than 2. The a/b ratio for this case stops at 2. Can I still use the table???
Case 8a, for instance, also gives values for "infinite" ratio.
Can someone please help me with my question.

Gert Kroon

RE: ROARKS table 11.4
For calculating deflections for the beam/infinite case, there is a 1/(1-nu^2) factor that enters in, applicable to "wide" beams where the compression and tension faces are not free to expand/contract laterally.
RE: ROARKS table 11.4
you could use a strip, 1" wide, as a beam, as mentioned above, which should be conservative.

I will see if this approach helps me.
