hi all(adsbygoogle = window.adsbygoogle || []).push({});

Basically I need to find the shear force and bending moment of a beam using octave. The length of the beam as well as forces and their distances are given. However the SF and BM must be calculated at every o.ooo5m. The forces can be Point Loads or Uniform Distributed Loads and there can be many forces of each type.

The data is given in a matrix eg:[ 2000N 5m] or [2000N/m 5m 10m].

This is what I have so far but it does not seem to be working out:

Positions = 0:0.0005:BeamLength

%Shear force from support reaction

ReactionShearForce = -ReactionForce

%shear force from PointLoads

for y = 1:1:length(Positions)

x = Position(1,y)

if x > PointLoads(:,2)

PointLoadsSection = PointLoads(PointLoads(:,2)>x,1)

end

end
