ACI 408.2R-92 (R2005)

This report summarizes the most recent research on bond behavior under cyclic loads. The report provides a background to bond problems, discusses the main variables affecting bond performance, and describes its behavior under cyclic loads. Two general types of cyclic loads are addressed: highcycle (fatigue) and low-cycle (earthquake and similar) loads. The behavior of straight anchorages, hooks and splices is included. Design recommendations are provided for both high and low cycle fatigue, and suggestions for further research are given.
