POD-based reduced order modeling of dynamic system

in this paper we study reduced order modeling of dynamic structural systems through the proper orthogonal decomposition POD technique. Principal component analysis is odopted to generate the reduced space where the equations of motion of the system are projected onto nuimerical results concerning the pirelli tower in milan excited by an earthquake are shown to get insights into the capability and efficiency of the proposed methodology.
