VIBRATION STUDIES ON JOLTER FOUNDATIONS

Vibration is a common occurence in an industrial plant. Studies on the dynamic response of foundation-soil systems have received special attention in the recent past. The attention has, however, been largely confined to studies of the response of foundations experiencing steady state dynamic loads. Relatively little information has been published on the design and performance of impulsively loaded foundations. The paper presents a study on existing jolter foundations in an industrial plant. A jolter is essentially an impact causing machine. Considering the limitations of the methods now in vogue in designing these foundations and the paucity of data required to make their rational analysis, it is felt that case study data from existing foundations provides valuable information on the basis of which their true behaviour can be evaluated. The paper includes an explanation of the problem, mathematical model used for computation as well as measurements of vibration conducted at site. It is shown that the "equivelent hammer analogy" is not applicable to foundations of machinery having a long duration of impact. /Author/
