Frequently Asked Questions
What is the weight of a W10X100 beam? 100 lb/ft (149 kg/m). A 40-ft length weighs approximately 4,000 lbs.
What is the section modulus of W10X100? Sx = 112 in³ (strong axis) and Sy = 40 in³ (weak axis). The plastic section modulus Zx = 130 in³ and Zy = 61 in³.
What steel grade is standard for W10X100? 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 W10X100? Ix = 623 in⁴ about the strong axis and Iy = 207 in⁴ about the weak axis. The radius of gyration is rx = 4.60 in and ry = 2.65 in.
