Advanced Charge Case

Calculatrice de fleche de poutre pour 3 Point Charges

Analyze a simply supported poutre avec three discrete point charges, including reactions, fleche, effort tranchant, et moment diagrams.

Use meters pour geometry, kN pour point charges, 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 = 4,500 cm^4.

Resultat

Linear superposition of three point-load responses

Load setup

Forme generale

F = F_point + F_distributed

Modele actuel

P1 = 6.00 kN @ 1.20 m; P2 = 10.00 kN @ 3.00 m; P3 = 6.00 kN @ 4.80 m. No distributed load.

Resultat

Max deflection = 8.01 mm

Internal response

Forme generale

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

Modele actuel

Max |M| = 22.20 kN*m, max |V| = 11.00 kN.

Resultat

Reactions solved at 2 support locations

Hypotheses du modele
  • The poutre is simply supported at both ends.
  • All three point charges act vertically in the same plane.
  • The model is linear elastic et based on Euler-Bernoulli poutre theory.
Outils associes
  • This page solves the combined response of three point charges on one portee rather than forcing the user into repeated single-charge calculations.
  • The response is assembled through a reusable advanced poutre solveur, so reactions et internal force diagrams stay coherent even when the three charges are asymmetric.
  • If the real poutre includes partial fixity, torsion, or large deformation effects, this one-dimensional elastic model should be treated as a preliminaire check.
