Conference paper


A simple and useful expression for the tangent stiffness matrix of a truss undergoing arbitrarily large deformation, as well as member’s buckling, is given. An arc length method is used to solve the tangent stiffness equations in the post-buckling range of the structural deformation. Numerical examples to illustrate the viability of the present approach in analyzing truss structures, simply, efficiently, and accurately, are given.
