An aluminum W310 x 202 (wide joint) column is subjected to an off-center axial load (P) as shown. Max Compressive stress in column: P max =σ1+ ec sec L 2r Calculated with that formula o=P/A → Average stress BE 2 A = 25800 mm → cross sectional area of the column e = 85 mm →→ eccentricity of loading c=170 mm →→ half depth of column r = 142 mm →→ turning radius of the cross section L = 7100 mm → the length of the column E = 71×10 Pa → modulus of elasticity If the maximum stress does not exceed 120 x 106 Pa, find the maximum load P the column can carry. Secant Method: E Start with = = 0.001 P(0) = 1000 P(1) = 2000 e P An aluminum W310 x 202 (wide joint) column is subjected to an off-center axial load (P) as shown.
