Abstract
This report describes a U-bar piping restraint element for the ANSR-II program. The element is intended for use primarily in analyses of pipe whip but can be used to model any uniaxial restraining device which provides inelastic restraint to structural motion in one direction (tension) while allowing unrestrained motion in the other direction (compression). The report contains a description of the element behavior, the theoretical formulation, and a computer program user's guide.
