Abstract: A method is presented to analyze the behavior and evaluate the safety of a rib-type anchorage system used in attaching the steel liner plate to the concrete wall in a prestressed or reinforced concrete containment vessel. The method presented is consistent with that of Doyle and Chu and utilizes the stress fall-off concepts examined by Young and Tate. A mathematical model is defined, and the analysis procedure is developed in step-by-step fashion up to the final determination of anchor displacements and factor of safety. A computer program was written to perform the calculations described. The method, as presented and programmed, requires that the load-deflection curve be idealized as either bilinear or trilinear. One linear panel is assumed to be buckled. The initial deflection of this panel plus the thicknesses and yield strengths of this and other panels are then specified.
