Frequently Asked Questions
The calculator uses fundamental beam bending theory, including the Euler-Bernoulli beam equation. It calculates section properties (area, moment of inertia) and applies material strength values to determine maximum safe loads based on bending stress limitations.
Safety factors account for uncertainties in material properties, unexpected loads, and construction tolerances. A typical factor of 2.5-3.0 ensures the beam can handle loads beyond the calculated theoretical capacity.
Yes, the calculator works for horizontal beams in various applications. For specialized cases like floor joists, you may need to consider additional factors like deflection limits and vibration control.
We use conservative average values from engineering references. For critical projects, always verify with material test reports or local building codes as strengths can vary by grade and manufacturer.
This version focuses on load capacity based on bending stress. For deflection calculations, you’ll need to consider additional parameters like modulus of elasticity and allowable deflection limits.
