W10×88 vs W10×100
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W10×100 is the heavier section at 100 lb per foot, versus 88 for W10×88 (12 lb/ft more).
Both are nominally 10 in. deep.
W10×100 has the greater bending strength: section modulus Sx of 112 in³ versus 98.5, about 14% more.
