Jinsi ya kukokotoa Beam Deflection
Beam Deflection ni nini?
Beam deflection calculates downward displacement under loading. Engineers use this to ensure beams don't sag excessively and meet serviceability requirements.
Fomula
The calculator applies beam deflection formulas: δ = PL³/(3EI) for cantilever
Mwongozo wa Hatua kwa Hatua
- 1Input beam type (cantilever, simply supported, etc.), load type, material properties, and geometry
- 2The calculator applies beam deflection formulas: δ = PL³/(3EI) for cantilever
- 3Results show maximum deflection and compliance with limits
Mifano Iliyotatuliwa
Ingizo
Cantilever, P=10 kN, L=3 m, EI=200 kN·m²
Matokeo
δ ≈ 45 mm
At L/4 deflection check
Makosa ya Kawaida ya Kuepuka
- ✕Using beam formula for wrong support conditions
- ✕Neglecting distributed loads when present
Maswali yanayoulizwa mara kwa mara
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.
