GE-99-13 A thesis submitted in partial fulfillment of requirements for the degree of Master of Engineering, School of Civil Engineering An analytical method is proposed for determining the pullout resistance/pullout displacement relationship of hexagonal wire mesh reinforcement, for both of PVC-coated and zinc-coated types. The parameters used in this analytical model were obtained from pullout testing programs, such as shear stiffness (ks), and initial slope of pullout bearing resistance (Eip). In addition, this method can predict the movement characteristics of both in PVC-coated and zinc-coated hexagonal mesh during pullout. On the basis of the deformation characteristic of hexagonal wire mesh, the movements and rotations of transverse wires were formulated. The displacements along the reinforcement were calculated by using the proposed deformation characteristic and the reinforcement axial stiffness. The friction resistance can be simulated by linear, elastic-perfectly plastic model. The hyperbolic model can be used to calculate the bearing resistance. The proposed analytical method is utilized for predicting the pullout resistance and elongation along reinforcement as well as effective reinforced length. Its validity is confirmed by the reasonable agreement between the predicted and measured pullout resistances. This method can be utilized in both silty sand and weathered Bangkok clay. From the predicted value, the percentages of the friction resistances to the total pullout resistance are 16% and 18% for PVC-coated and zinc-coated hexagonal wire mesh, respectively. Consequently, the bearing resistances are 82% and 84% of the total pullout resistance for zinc-coated and PVC-coated hexagonal wires, respectively. The ratios between friction and bearing resistance are 22% and 19% for the zinc-coated and the PVC-coated wire meshes, respectively. The total pullout resistance in the zinc-coated wire mesh is higher than PVCcoated by approximately 20%. The total pullout resistance in the weathered Bangkok clay are 40% and 45% higher than in the silty sand for PVC-coated and zinc-coated type, respectively. For Comparison in the silty snad backfill, the friction resistances are 25% and 21 % of the total pullout resistance for zinc-coated and PVC-coated meshes, respectively. Furthermore, the corresponding values of bearing resistances are 75% and 79% of the total pullout resistances.
