Structural Beam Load Calculator

Estimate the load-bearing stiffness of a simply supported structural beam based on its span, cross-section, and material. Use this when sizing floor joists, headers, or steel beams for construction projects.

Civil

Column Buckling Load Calculator

Calculates the critical (Euler) buckling load for a slender structural column given its material stiffness, cross-section, length, and end-fixity conditions. Use it to check column stability in steel, timber, or concrete frames.

Modulus of Elasticity (MPa)

Moment of Inertia (cm⁴)
