W14×176 vs W24×176
A side-by-side comparison of two AISC wide-flange beams, 16th Edition. Detailing dimensions to the nearest 1/16 in.
W14×176 and W24×176 both weigh 176 lb per foot, so the choice comes down to depth and stiffness rather than weight.
W24×176 is the deeper section at a nominal 24 in., versus 14 in.
W24×176 has the greater bending strength: section modulus Sx of 450 in³ versus 281, about 60% more.
