W14×82 vs W14×90
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W14×90 is the heavier section at 90 lb per foot, versus 82 for W14×82 (8 lb/ft more).
Both are nominally 14 in. deep.
W14×90 has the greater bending strength: section modulus Sx of 143 in³ versus 123, about 16% more.
