compression buckling loads for horizontal beams
compression buckling loads for horizontal beams
(OP)
I am looking for methods to determine the compressional critical buckling load for a horizontal box beam, includingthe effect of gravity that causes the beam to deflect down under its own weight. Please advise if you know of such an analysis or can suggest how to proceed.
Thank you
Thank you

alternatively, you can calc the beam as a beam-column (a conventional beam with transverse loads and axial compression).

Thus I am concerned that the weakening effect may be significant but am not convinced that I have captured it correctly.
I may try to go after an energy based method, any suggestions on doing that??
Thanks to all readera and for comments.

You might also refer to Roark's Formulas for Stress and Strain for various column formulas. (The column formulas specific to a material or code may be out of date.) He discusses combined bending and buckling and then says "Because these and other uncertainties generally preclude a precise solution, it is common practice to rely upon some interaction formula, such as one of those given below."
