beamGLForces function

beamGLForces

Uses nodal displacements to determine global and local forces at each node

beamGLForces(beamP, beamT, Y, MoI, Length, GMat, BUDL, BND)

Arguments

• beamP: Matrix (2 x n) of beam coordinates.
• beamT: Matrix (2 x n) containing the number of the coordinate point as shown in beamP that connect to form a given beam (Discretization table).
• Y: Elastic Modulus of material
• MoI: Moment of Inertia
• Length: Length of beam
• GMat: Global stiffness matrix
• BUDL: Column matrix for beam distributed load
• BND: beam nodal displacement, output from function "beamNodeDis"

Returns

Matrices of global and local forces. (Results in kN) - GForce: Large global force matrix.

• Lforce: Large local force matrix.

Examples

data(beamGeo)
data(beamDime)
data(beamsUDL)
data(beamND)
data(beamGloMat)

Length = beamDime$Length
MoI = beamDime$MomentofInertia
BUDL = beamsUDL
BND = beamND
GMat = beamGloMat

GLforce = beamGLForces(beamGeo$beamP, beamGeo$beamT, beamGeo$Y, MoI, Length, GMat, BUDL, BND)
