This paper presents the vibration response analysis of double-walled pipe models subjected to external excitation. The governing equations of motion are introduced in general form to comprehend different shell theories of Flugge, Love and Donnell by use of tracing parameters, and an approximate solution for the frequency response is derived for the pipe system problem. The modeling of filling material between two walls is considered, and the coupling effect of two shells through the filling material is discussed.
