Frequently Asked Questions
What is the weight of a W16X100 beam? 100 lb/ft (149 kg/m). A 40-ft length weighs approximately 4,000 lbs.
What is the section modulus of W16X100? Sx = 175 in³ (strong axis) and Sy = 35.7 in³ (weak axis). The plastic section modulus Zx = 198 in³ and Zy = 54.9 in³.
What steel grade is standard for W16X100? Typically ASTM A992 (Fy = 50 ksi, Fu = 65 ksi) for W-shapes. Also available in A572 Grade 50 or A36. Verify with mill certificate.
What is the moment of inertia of W16X100? Ix = 1490 in⁴ about the strong axis and Iy = 186 in⁴ about the weak axis. The radius of gyration is rx = 7.10 in and ry = 2.51 in.
