This is a MATLAB project to implement the generalized stiffness method for finite element analysis of a
structure. The implementation was considered as an objective function for a numerical optimization of a
specific frames dimensions. In retrospect, the choice to use it as the objective, instead of a using it
as a limiting constraint was not helpful in optimizing the design. The optimization of the frame almost
always
approached the lower bounds of the member lengths, attempting to make the frame as small as possible and
thus reducing deflection.
Using the FEA implementation to constrain the maxmimum stress present in any given element, while
minimizing material size and length, would have been a far more useful application of the technique.
Unoptimized frame design.
