Frequently Asked Questions – Beam Load Calculator

What beam support conditions does this calculator assume?

This calculator assumes simply supported beam conditions (pinned support at one end, roller support at the other). For fixed or cantilever beams, different calculations would be needed.

How accurate are these calculations?

Calculations use standard beam theory formulas and provide good estimates for preliminary design. For final designs, always consult structural engineering standards and consider factors like safety margins, creep, and dynamic effects.

What’s the difference between point and uniform loads?

Point load is concentrated at one location (like a column). Uniform load is evenly distributed (like floor weight). Triangular load varies linearly (like hydrostatic pressure).

Why is my calculated stress higher than material strength?

This indicates your beam may fail! Consider increasing dimensions, changing material, or reducing load. Always include safety factors (typically 1.5-3x) in actual designs.

How do I account for multiple load types?

For complex loading, calculate each load type separately and use superposition principle (add results). Professional software may be needed for advanced cases.
