Paano Kalkulahin si Beam Deflection

Ano ang Beam Deflection?

Beam deflection calculates downward displacement under loading. Engineers use this to ensure beams don't sag excessively and meet serviceability requirements.

Pormula

The calculator applies beam deflection formulas: δ = PL³/(3EI) for cantilever

Step-by-Step na Gabay

  1. 1Input beam type (cantilever, simply supported, etc.), load type, material properties, and geometry
  2. 2The calculator applies beam deflection formulas: δ = PL³/(3EI) for cantilever
  3. 3Results show maximum deflection and compliance with limits

Mga Nalutas na Halimbawa

Input
Cantilever, P=10 kN, L=3 m, EI=200 kN·m²
Resulta
δ ≈ 45 mm
At L/4 deflection check

Mga Karaniwang Mali na Dapat Iwasan

  • Using beam formula for wrong support conditions
  • Neglecting distributed loads when present

Mga madalas itanong

Why limit beam deflection?

Excessive deflection causes floor sag, cracks, misalignment. Building codes limit deflection to L/240-L/360.

How does moment of inertia affect deflection?

Doubling I reduces deflection by half; this is why tall I-beams resist deflection better than wide ones.
