Cyclic properties of reconstituted sand and clay were measured in a double specimen direct simple shear (DSDSS) device for small-strain testing, recently developed at the University of Rome “La Sapienza”. The original version of the DSDSS device was designed and built in 1994 at the University of California at Los Angeles (UCLA). The objective of the paper is twofold: (a) to assess the repeatability of the testing technique with the new DSDSS device; (b) to compare the results of simple shear testing obtained in the original and new DSDSS device. Typical results of the experimental investigation are presented in terms of stress-strain hysteresis loops as well as in terms of traditional cyclic parameters such as maximum shear modulus (G0), secant shear modulus (Gs), normalised shear modulus (Gs/G0) and damping ratio (D).

Abstract
Cyclic properties of reconstituted sand and clay were measured in a double specimen direct simple shear (DSDSS) device for small-strain testing, recently developed at the University of Rome “La Sapienza”. The original version of the DSDSS device was designed and built in 1994 at the University of California at Los Angeles (UCLA). The objective of the paper is twofold: (a) to assess the repeatability of the testing technique with the new DSDSS device; (b) to compare the results of simple shear testing obtained in the original and new DSDSS device. Typical results of the experimental investigation are presented in terms of stress-strain hysteresis loops as well as in terms of traditional cyclic parameters such as maximum shear modulus (G0), secant shear modulus (Gs), normalised shear modulus (Gs/G0) and damping ratio (D).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
