Predicting the long-term strength of a geogrid using the stepped isothermal method
By means of 12 stepped isothermal tests, each one lasting about 24 h, a long-term design strength of 71.9 kN/m has been derived for a polyester geogrid, prior to the application of reduction and safety factors. In addition to ERA's detailed comments above it is recommended that: the procedure for SIM is standardised, particularly since the analysis of the data includes correction factors which allow scope for choice. SIM data should only be accepted for properties and materials where there is a published validation of the method by comparison with conventional methods. So far this applies only to the creep strain of polyester geogrids. All creep and creep-rupture data derived using SIM should be stated as such.
