Slenderness of columns
Slenderness of columns
(OP)
I tried to find (I am not good at it) CosmosXrpress forum but could not.
- Could anybody give me link to cosmosexpress forum ?
- More important - I need a quick answer: Does the CosmosXpress considers slenderness of columns ---> buckling when columns are subject to compression load ? I guess it does but I would like to hear it from some gurus.
Thaks in advance.

RE: Slenderness of columns
COSMOSXpress is very limited. Probably does not have buckling. I haven't seen it.
RE: Slenderness of columns
The program did NOT finished (I tried it twice) - this time I am getting message: Not enough boudary conditions.
My guess it - it means the vertical column simply collapsed ?
RE: Slenderness of columns
I would be very very wary of using Cosmos express in this way.
There are some very simple calculations available for buckling by (amongst others) a chap named Euler.
In its simplest form for pinned ends
Pcritical=(pi^2EI)/(l^2)
Where Pcritical is the critical buckling load, E is modulus (207 GPa for steel) and I is the second moment of area of the column.

Euler's Formula P/A = Cpi^2E/(L/r)^2
Depending on your specific column geometry their are several conditional set ups.
