Background and Need
This report unveils the results of a comprehensive 2.5-year research project funded by the NCMA Foundation. Utilizing full-scale wall testing, the study provides a rare, deep dive into the mechanical response of SRWs when lateral loads are applied directly through post and beam systems. The research is the first phase on this topic and will help the industry understand with data how the wall as a whole, the facing, soil and reinforcement behave depending on the geogrid reinforcement spacing and loads.
