DESIGN CRITERIA FOR FLEXIBLE UTILITY CONNECTIONS

Abstract

The existing design of flexible utility connections used in naval installations incorporates a flexible bronze hose hanging freely within a corrugated metal tube so that it can move without being highly stressed at the soil-structure interface. A study was made of this design and of possible modifications to it. Theoretical predictions were formulated for flexibility and dynamic strength; the theories were tested and partially verified experimentally in the laboratory. The flexibility of a hose was related to the manufacturer's specified minimum allowable bend radius. The dynamic strength was expressed in terms of peak acceleration and hose weight and length in a semiempirical relationship suitable for use in design. It is recommended that the results of the present study be incorporated in an appropriate design manual, subject to verification by full-scale field tests, and that a summary be compiled of means to predict the relative displacements between a buried structure and the surrounding soil.
