Abstract
The use of polymeric geogrids in reinforcement applications is progressing rapidly with the current commercial availability of the products of at least ten different manufacturers. While all of these products consist of an interconnected set of longitudinal and transverse ribs, their similarity ends at this point. Major variables consist of rib size and strength, aperture size, type of polymer, and method of joining the intersecting ribs.
This paper attempts to model the use of a ‘generic’ geogrid in the anchorage, or pullout, mode of behavior. It does so by deriving an incremental finite-element formulation to simulate the non-linear response of the geogrid to pullout. Polynomial and hyperbolic functions are used to represent the load-extension behavior of the geogrid and the soil-geogrid-interaction frictional and bearing properties. Three models are incorporated in the analysis to simulate the deformation of the transverse ribs. Highly flexible ribs are assumed to take a parabolic shape and to act as strings, whereas short stiff ribs are considered not to deflect during pulling. Intermediate cases are analyzed by assuming the ribs to behave as beams deflecting under load.
Upon development of the program, it is illustrated on an example geogrid. The behavioral trends of the various components of friction and bearing are generated with respect to the percentage mobilized of the pullout load. Of major interest is an understanding of the relative contribution of the various components, particularly the amount of force that must be transmitted through the rib junctions.
