Abstract

The basic elements of resilient mounting systems are described and various measures for quantifying the effect of such systems defined. Using electrical analogue circuits, the calculation of these measures is illustrated. With special reference to resilient mounting systems in buildings, under specified assumptions, improved analogies for system elements are derived, thus arriving finally at a complete electrical analogy of a compound mounting system. Some results of computer calculations, as well as a greatly simplified method suitable for manual computation, are presented. The second section of the paper describes the application to practical problems of the approach developed in the first section. Data from present standards for maximum permissible noise and vibration levels are given in suitable form. Nomograms for calculation of the lowest eigenfrequency of concrete floor fields are also given.
