Expert Answer

---

To determine the buckling force resistance of a rectangular hollow sectioned compressed column,

Euler's formula for buckling:

  


Where:
Pcr is the critical buckling load or force
E is the modulus of elasticity of the material
I is the moment of inertia of the cross-sectional area
L is the length of the column between the fixed ends
K is the effective length factor, which depends on the end conditions of the column.


Rectangular hollow sectioned column, the moment of inertia I and the effective length factor K depend on the dimensions of the cross-section and the end conditions.

Cross-section

width b=14.1 cm

height H = 3350 mm

wall thickness t= 1.90 cm.
