“…The properties of these geogrids are speciˆed based on: (i) rib cross-sectional area, (ii) grid opening size, (iii) tensile strength, and (iv) type of material composition. Based on the scaling considerations presented elsewhere by Viswanadham and Jessberger (2005), a model geogrid layer MG1 representing bandwidth of properties of commercially available geogrids has been selected and used in the present study. While scaling down the model geogrid, it was seen that it simulates both: (i) tensile strength-strain behaviour and (ii) frictional bond behaviour, which was considered by matching percentage open areas in model and prototype geogrids approximately.…”
