The prediction of the response of aircraft fuselage structures to acoustic excitation is of interest because of the resulting sound radiation and fatigue problems. A fuselage structure essentially consists of a cylindrical shell stiffened by circumferential frames and longitudinal stringers. This paper is concerned with determining the response of a portion of such a structure to a random pressure field. The model is a rectangular, singly curved, orthogonally stiffened panel. It has six curved. channel section frames and sixteen straight, Z-section stringers. The response of this model to discrete frequency excitation has previously been measured [1] . Detailed measurements were made of part of the structure between two adjacent frames. A theoretical analysis of this curved skin-stringer array using the finite strip method is presented in reference This paper presents a finite element analysis of the complete model. In order to minimize the computing, the model is treated as a two-dimensional periodic structureThe computed response is com-paterl with some recent measurements.
