This research has focused on the development of feasible approaches to the utilization of computer algebra to derive the Greens Function of interconnected structural systems. The key objectives of the effort were to 1 develop MACSYMA-based routines for analyzing the Greens functions of structural systems consisting of uniform beams supported at discrete locations of linear springs and 2 extend these techniques to include attachments of linear spring-mass-damper substructures to uniform beams. Both of these objectives were met. This final report summarizes the methodologies that were developed, including appendices which present the MACSYMA routines illustrating the application of these methodologies, as well as paper which was presented in Singapore at the International Noise and Vibration 89 Conference. Keywords Structural dynamics.
