Employing a method of vibration testing due to Kennedy and Pancu, with elementary extensions, forced damped modes of vibration of unit fabricated structures have been studied. Theoretical and practical procedures associated with the tests are discussed and the response vector diagrams and mode shape diagrams presented for the third bending mode of vibration of single and combined unit structures. The existence and accuracy of damped modes of vibration are discussed. Test results indicate that by applying this vibration testing method, approximate forced damped modes of vibration of unit structures are uncovered. The dynamic characteristics of these modes will be suitable for use in design and development studies.
