Web Buckling
Web Buckling
(OP)
I have a machined rib and want to check the web buckling. What dimension should I use for the web width? Usually I would use the dimension from the mid-line of the surrounding stiffeners but a less conservative view may be to use the dimension from the inside surface of the stiffeners. What is the general view?
Also rather than assuming SS edge conditions is there a way to calculate a rotational stiffness value so that the edge condition is somewhere between SS and fixed.

RE: Web Buckling
if the stiffener is thicker than the panel then you have more rotational support along the edge of the panel. fully fixed is clearly the less conservative thing to assume. one thing to consider is waht are the consequences of buckling ... if a panel on the rib buckles (elastically) would the rib collapse ?

A quick search on google did not find anything. Can you suggest how I get a copy.
