- Abstract:
- The dynamic response of cantilever retaining walls under seismic actions was studied by means of 1-g shaking table at the Earthquake and Large Structures Laboratory (EQUALS) which is part of the Bristol Laboratories of Advanced Dynamics Engineering (BLADE), of the University of Bristol. The soil material used to build the geotechnical model consists of dry, yellow Leighton Buzzard (LB) Fraction B. This soil has been used extensively in experimental researches on shaking table. However, no information on the dynamic behaviour at low confining stress is available for this soil. To fill this gap, dynamic laboratory tests were performed at the Soil Dynamic Laboratory (DynaLab) of the University of Naples Federico II. The main purpose of this experimental activity was to evaluate the dynamic soil behaviour of LBS-fraction B, by means of Resonant Column tests (RC) and Torsional Shear tests (TS) at several confining stresses and different strain levels.
