Units for force
Example: \( N, kN, ... \)
Units for length
Example: \( m, mm, ft, in, ... \)
$$L_0 = $$
\( \)
Free buckling lenght (\( L_0 = \beta \cdot L\) with \( \beta = 0.5, .., 2.0 \) )
$$J_{min} = $$
\(^4 \)
Minimum (inertia moment) second moment area for section considered
$$E = $$
\(/^2 \)
Young Modulus for material considered (ex. steel \(E = 200 - 210 GPa \) )
$$N_{cr} = \pi^2 \frac{E J_{min}}{L_0^2} = $$
NAN
Reverse Engineering
$$N_{ed} = $$
Axial force
$$\alpha_{cr} = $$
Buckling factor (usually form Buckling Analysis)
$$N_{cr} = \alpha_{cr} \cdot N_{Ed} = $$
0
