Analytical modeling for predicting the pullout capacity between hexagonal wire mesh and sand

The pullout clamping system was installed inside the pullout box with confinement from the fill material hereinafter called "in-soil pullout test" which significantly reduced the necking phenomenon during the pullout test. The analytical models for predicting the in-soil pullout resistance were developed based on the observed deformation characteristics of hexagonal wire mesh during large scale in-soil pullout tests. The pullout resistance of the hexagonal wire mesh reinforcement consists of two components, namely: friction resistance and passive bearing resistance. The frictional resistance versus relative displacement relationship of a hexagonal wire mesh was modeled by a linear elastic-perfectly plastic model while the passive bearing resistance of the individual bearing member was modeled by a hyperbolic function. Comparisons were then made between the laboratory in-soil pullout test results with the corresponding data obtained from the analytical modeling methods. Good agreements were obtained between the experimental and predicted data.
