Paper Details

The primary aim of this research is to evaluate Pullout capacity of Deformed and Plane steel bars embedded in tireshred sand mixture. Metallic (strip and grids) and Geo-synthetics are commonly used as reinforcement in mechanicallystabilized earth walls.in this research locally available Steel bars are used. Tire shreds sand mixture is used as backfillmaterials. Pullout resistance is one of the major causes of failure in MSE walls. Pullout resistance depends upon interactionbetween reinforcement and backfill Materials. By pullout tests we can determine the pullout resistance. Large scale testembankment was constructed at UET laboratory. large scale test embankment has 4ft x 3ft x 5ft dimensions. The wall of testfacility was made of steel. Three sides of the test facility were welded to each other. The facing is made of steel plate and isremovable. Pullout tests are performed on deformed and Plane steel bars at varying normal Pressure. Normal load is appliedthrough hydraulic jack #4 and #6 dia of Bars of both plane and deformed steel are used. Pullout load is applied throughhorizontally placed hydraulic jack. The pullout load is measured by the load cell attached to the hydraulic jack. The pulloutresistance increases with increase in normal load.
