SFBMD(forces,distlo​ad,len)

Draws Shear Force and Bending Moment Diagram of a Beam

%Shear Force and Bending Moment Diagram (SFBMD)
%--------------------------------------------------------------------------
% Draws the Shear Force and Bending moment diagram of beams subject to
% Concentrated loads/moments at the ends as well as uniform distributed loads
% along the beam in all three directions.
%
% SYNTAX
% SFBMD(option,forces,distloads,len)
%
% INPUT
% [forces] : Beam End Forces and Moments [fy1,mz1,fy1,mz2]
% [distloabd]: Distributed loads [wy]
% [len]: Length of the beam
%
% OUTPUT
% subplot 1: Shear Force Diagram
% subplot 2: Bending Moment Diagram
%
% The function can be chnaged quite easily to include it in any finite element program.
%
% EXAMPLE
% Cantilever with distributed load; SFBMD([0,0,0,0],-1,10)
% Cantelever load with concentrated force at the end; SFBMD([1,10,-1,0],0,10)
