The pullout behavior of mechanically stabilized earth (MSE) structures is very complicated and depends on many parameters which related to the backfill soil properties, the reinforcement characteristics and the interaction between them. This paper investigates the pullout behavior of many soil reinforcements under static and repeated loading. Four types of steel reinforcements were studied: Strip, W-shaped, ribbed and punched. The results obtained show that the change of the shape of reinforcement may improve the pullout resistance of MSE structures. Therefore, the best performance was obtained by the ribbed and the punched reinforcements, under static loading as well as repeated loading.
