This report presents a spectrum of design examples of steel embedments based on Appendix B of ACI 349-85. Appendix B ws developed to better define the design requirements for steel embedments. Revisions are periodically made to the code as a result of on-going research and testing. As with other concrete building codes, the designor embedments attempts to assure a ductile failure mode so that the reinforcement yields before the concrete crushes. In embedments designed for direct loading, the concrete pull-out strength must be greater than the strength of the tensile stress component. Appendix B also covers cases where ductile failure modes cannot be assured, by reducing the allowable load carrying capacity to assure a larger factor of safety. The format for each example follows the format of the Strength Design Handbook, SP-17, and provides a reference back to the code paragraph for each calculation procedure.
