Steel strips are one type of reinforcement used to stabilizeaggregate backfill through anchorage. In the current MSE wall design, pullout capacityof steel strips is evaluated to ensure internal stability of the reinforced mass. Thepullout resistance of reinforcement is expressed in terms of pullout resistance factorthat measures the reinforcement-backfill interaction. This pullout resistance factor iscommonly determined by performing pullout tests
