I have calculated the weight based deflection and then added the moment caused by this deflection with the critical compressive load and found that moment to be lower than the moment caused by the weight, by about a factor of three.
Thus I am concerned that the weakening effect may be...
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
