Fixed-Fixed Poutre Point Charge Fleche Calculatrice
Estimate reactions, end moments, fleche, effort tranchant, et bending response pour a fixed-fixed poutre sous a point charge.
Use meters pour geometry, kN pour point charge, GPa pour E, et cm^4 pour I.
Assumptions & Limits
- The model represents 2D bending response only et does not include torsion.
- Appuis are idealized as analytical boundary conditions.
- Construction stages, nonlinearity, et settlement effects need a more detailed model.
Reference Basis
- Documentation: Advanced poutre methodologie
- Documentation : revue technique
- Matrix rigidite method references
- Elastic poutre theory references pour validation checks

Beam model
K d = F
Supports: Left fixity @ 0.00 m, Right fixity @ 5.00 m. E = 210.0 GPa, I = 6,200 cm^4.
Euler-Bernoulli beam with fixed end restraints
Load setup
F = F_point + F_distributed
P = 12.00 kN @ 2.50 m. No distributed load.
Max deflection = 0.60 mm
Internal response
M(x) = E I y''(x), V(x) = dM/dx
Max |M| = 7.50 kN*m, max |V| = 6.00 kN.
Reactions solved at 2 support locations
- Both poutre ends are fully fixed in rotation et vertical displacement.
- The point charge acts vertically at the selected coordinate.
- The model assumes constant E et I along the member.
- This page addresses fixed-fixed poutre behavior directly instead of approximating it avec a simply supported poutre et correction factors.
- Because the appui restraints are explicit, the solveur also returns fixed-end reaction moments rather than only vertical reactions.
- Real end fixity may be lower than ideal full fixity, so connection flexibility should still be judged separately.
