Steel-plate composite (SC) walls can be anchored to reinforced concrete (RC) foundations using lap splice anchorages. Researchers in Japan have conducted extensive large-scale tests to evaluate the strength and ductility of these lap splice anchorages for the critical loading of cyclic axial tension. The parameters included were the tie bar reinforcement ratio, the clear distance from the dowel bars to the steel plates, and the embedment length. The experimental results are presented in this paper in detail, and analytical models are benchmarked to predict their behavior. Additional large-scale tests are conducted to further demonstrate the strength and ductility of lap-splice anchorages with adequate tie bar ratios and embedment length but significant eccentricity (distance between dowel bars and steel plates). The benchmarked models are used to gain additional insight into the behavior and force transfer in the lap-splice anchorage. The results from all the experimental and analytical investigations are used to provide design and detailing recommendations for lap-splice anchorages and to obtain ductile behavior.
