| Abstract | An analytical model for predicting the pullout resistance of hexagonal wire mesh
reinfo1~cement for both galvanized and PVC-coated types has been proposed. The
influence of transverse wires rotation was expressed in the deformation characteristic of
hexagonal wire mesh reinforcement. The displacement along the reinforcement was
calculated by using the proposed deformation characteristic corresponding to the
reinforcement axial stiffness. The mobilized bearing resistance was calculated by a
proposed hyperbolic bearing resistance/displacement relationship modified from
Wongsawanon (1998). The mobilized friction resistance was simulated by linear, elasticperfectly
plastic model. Some relevant parameters for the analysis were verified by
pullout test with specially designed specimens. The validity of the method is confirmed by
good agreement between calculated values and actual test results. The percentages of the
friction resistance to the total pullout resistance were analytically obtained as 25% and
21 % for galvanized and PVC-coated hexagonal wire mesh reinforcements, respectively,
and compared with the corresponding values of up to 46% and 37% predicted by
Wongsawanon (1998). In addition, the tension in reinforcement was calculated by using
limit equilibrium analysis. The tension was evaluated equal to the total resistance of
surrounding soil behind the considered section. The computed values of tension were
validated by the estimated tension from the measured strains data with the stress/strain
relationship of an individual wire in hexagonal wire mesh. The effective embedment
lengths and pullout displacement to mobilize the desired pullout resistance of hexagonal
wire mesh reinforcement under different applied normal pressures were also be
determined by the proposed analytical model. |
