Local buckling of tubulars

[Theozz]

Hi All,

Can anyone assist with this. I have a frame (comprising of a tubular section)supported on a concrete block, global bending stress checks are OK but would like to check local buckling/ovalisation stress to make sure that the tubular will not buckle espercially at the edges of the concrete block.
Any formulations/article or literature on such a scenario would be much appreciated.


Thank you

Pretty much all the codes (be it steel or otherwise) have a means to check localized buckling. In AISC, there are limiting width-thickness ratios. Allowable stresses depend (to a degree) on these.

Apparently your Internet Country Domain is Netherlands . If so, EC- 3 provides the ratios for local buckling .

The following is excerpt from SCI 363 Steel bldg design data ..

Note: SCI 363 Steel bldg design data is also attached.

Thank you all.
