Note: 439.3R-91 is Out of Print. However, a PDF version is available.
The objective of this report is to provide engineers with basic information about mechanical connections and the types of proprietary splice devices currently available. Since these splice devices are proprietary, the information herein has not previously been presented in such an assembled and detailed format. Reasons for using mechanical connections are discussed as well as various engineering considerations that must be made when specifying mechanical connections. Both "compression only" and full "tension-compression" splices are examined. Splice devices are described in terms of their configuration, procedure for splicing, clearance requirements, and other characteristics. Illustrations of the various splice devices are included.
