Easily determine essential square tube section properties such as area, moment of inertia, and section modulus for structural analysis and design. Our free online calculator provides accurate results for hollow structural sections (HSS), simplifying engineering calculations for various applications.
Formula:
For a square tube with Outer Width (W) and Wall Thickness (t):
- Area (A) = W² - (W - 2t)²
- Moment of Inertia (Ixx = Iyy) = (W⁴ - (W - 2t)⁴) / 12
- Section Modulus (Zxx = Zyy) = I / (W / 2)
- Radius of Gyration (Rxx = Ryy) = √ (I / A)
