Predicting Vibrations of Soil and Buildings Excited by Machine Foundations Under Dynamic Loads

This paper presents a new method that predicts the vibrational effects on existing soil, building and equipment from a designed machine foundation when it will be installed at a specific site. The method requires development of certain experimental data at an industrial site and subsequent computerized data reduction. The results are complete vibro-records at the locations of interest. The basic prerequisite of the suggested method is an experimental determining of impulse responses of soil and structures. The use of this response gives to an engineer a chance to consider heterogeneity and multiformity of soil properties. The accepted assumptions have been experimentally based. The general set-up of the way of predicting and the examples of predicting soil vibration has been described. The application of the suggested method gives the possibility of a determination of safe distances from machine foundations to sensitive units
