Euler-Bernoulli peak deflection for prismatic beams — four standard load cases.
Beam Deflection Calculator öffnen →Schritte
- 1Pick the idealized case closest to your support and loading condition.
- 2Gather L, E, I, and load intensity with consistent SI units.
- 3Apply the matching closed-form equation and compute peak deflection.
- 4Check whether result magnitude is reasonable for the assumed section stiffness.
- 5Escalate to richer modeling for deep beams, complex supports, or strict code checks.
Beispiele
- Fast stiffness comparison between two candidate section inertias.
- Order-of-magnitude deflection check before committing to finite-element setup.
Was vermeiden
- Using wrong end-condition formula for the same load.
- Supplying I in mm^4 while E is in Pa without conversion.
- Treating elastic estimate as a full strength-and-serviceability sign-off.

FAQ
Does this include shear deformation?
No. The implementation is Euler-Bernoulli small-deflection only.
Can I combine multiple load patterns?
Use superposition carefully outside this single-case UI or move to a full analysis workflow.
