Creating a more efficient reinforcement for Mechanically Stabilized Earth (MSE) Walls is important because it will reduce the amount of material needed to construct MSE walls, and will reduce overall construction costs for companies and contractors.
This thesis explores four main geometries of metallic crimped and metallic crossbar type reinforcement constructed with both, smooth steel and #4 rebar steel. Metal round bar was chosen because, compared to metallic rectangular strip reinforcements, there is less surface area in contact with the soil which will then reduce the amount of corrosion loses. Throughout testing, it was found that crimped metal round bar was able to produce the required pullout resistance but created too much extensibility (the amount of length the crimps straightened). The reinforcement made with crossbars and metal round bar were found to produce the required amount of pullout resistance with little to no extensibility.
