Foundations for auto shredders

Abstract

Unbalanced forces developed by hammer wear and impact must be resisted by auto shredder foundations. Methods for estimating the impact forces are described. Because of different soil conditions, a concrete mat, a concrete block, and a pile-supported foundation system were adopted at three different construction sites. The design procedures involved in determining the dynamic response for each type of foundation are illustrated by examples. Vibration measurements made on the pile-supported foundation after construction permitted comparisons of prototype motions with design predictions.
