Modal decomposition of buckled shapes: The method of the equivalent nodal forces
Abstract eng: The paper presents the development of a method for the decomposition of a random deformed shape of a thin-walled element into the contributions of different classes of buckling modes. In this method, these classes encompass five types: local, distortional, global, transverse extension and shear modes. These different types of buckling modes are generated by imposing precisely defined nodal forces onto the structural element, forcing it to deform in a desired mode. The full collection of buckling modes forms a orthogonal set of basis vectors of the complete deformation space. Although the proposed method is more general in its application, it is here presented within the context of the finite strip method.
