SEISMIC DESIGN AND THE STRENGTH OF GEOSYNTHETIC REINFORCEMENTS

Tests on polyester and polyethylene geogrids for reinforcement applications show that a geosynthetic under sustained load retains its strength over its useful lifetime. This strength is unaffected by seismic loading provided that the total load and duration do not exceed that obtained from the creep-rupture curve. Simulated seismic loads lead to a step change in strain in the geosynthetic, part of which is recovered instantly and the rest over a period of time. These findings have a profound effect on the manner in which reinforced soil is designed for seismic loading. For the covering abstract see ITRD E117244.
