Conference Paper

Three large gyratory ore crushers were mounted on a common reinforced concrete hollow box base 11. 0 multiplied by 20. 0 multiplied by 13. 8 m. This base formed an integral part of an irregular, about ten storey high industrial reinforced concrete framed structure. The objective of the original analysis was to determine the fatigue resistance of the structure, the acceptability of the vibrations to human response and its compliance to the criteria for machine bearing displacements. This paper, however, deals only with a comparison between the predicted and measured dynamic displacements.
