Hi all,
I have a fairly easy question. Done a buckling analysis of a frame.
I usually take the buckling length and feed it into the member type
Wondering if length should be ignored, specifically, if I see that buckling is about the z axis, should the length be about y axis? This seems to be in line with the theory, but wanted to double check.
The height of the col is 5 m.
Thank you!!!
Hi @goworav900
In both cases, Alpha_cr is < 10, so you must perform a Pdelta analysis.
In the first case, it's a local buckling not to take into account.
In the second, it's a global buckling, and the buckling length value is closer to reality.
However, this value should not be used directly to feed the member type, but instead, the value based on the stiffnesses of the colomn and adjoining members should be used.
