Advanced Charge Case

Triangular Charge Calculatrice de fleche de poutre

Estimate fleche, reactions, effort tranchant, et bending moment pour a simply supported poutre sous a full-portee triangular charge.

Use meters pour geometry, kN/m pour the peak triangular 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.

Calculation Method

Beam model

Forme generale

K d = F

Modele actuel

Supports: Left support @ 0.00 m, Right support @ 6.00 m. E = 210.0 GPa, I = 4,800 cm^4.

Resultat

Euler-Bernoulli beam under linearly varying distributed load

Load setup

Forme generale

F = F_point + F_distributed

Modele actuel

No discrete point loads. w(x): 0.00 to 7.00 kN/m over 0.00-6.00 m.

Resultat

Max deflection = 5.87 mm

Internal response

Forme generale

M(x) = E I y''(x), V(x) = dM/dx

Modele actuel

Max |M| = 16.18 kN*m, max |V| = 13.14 kN.

Resultat

Reactions solved at 2 support locations

Hypotheses du modele
  • The poutre is simply supported at both ends.
  • The triangular charge ramps from zero at the left end to the peak value at the right end.
  • The model is linear elastic avec constant member rigidite.
Outils associes
  • This page captures a courant charge pattern that generic uniform-charge calculators miss: one-way ramps such as pressure buildup, fill, or tapered tributary loading.
  • The solveur resolves reactions et diagrams directly from the triangular charge rather than replacing it avec an equivalent uniform shortcut in the UI.
  • If the real triangular charge is partial, reversed, or combined avec multiple other charge patterns, it should be modeled separately or through a more general poutre analysis outil.
