Cyclic Simple Shear Testing of Granular Materials
Geotechnical Testing Journal, 1986Abstract Developments to a pneumatically operated simple shear apparatus for dry granular materials allowing application of cyclic shear and normal stresses are described. Boundary transducers were of only limited success for stress measurement so a prediction method for complete description of the stress state was used. Tests on uniform

A Cyclic Undrained Simple Shear Testing Method for Soils
Geotechnical Testing Journal, 1989Abstract An undrained simple shear testing method for soils using a torsional shear apparatus is described, in which a hollow cylindrical specimen is sheared under plane strain conditions without deforming and rotating all horizontal planes.

A New Cyclic Simple Shear Test Procedure with Multidirectional Loading
Geotechnical Testing Journal, 2019Abstract This article presents a new procedure for cyclic simple shear tests with a change in the loading direction. For the experimental investigation of sand under drained condition, a conventional simple shear test device (unidirectional simple shear) was used.

Cyclic Simple Shear Apparatus for Low-Strain Soil Tests
Transportation Research Record: Journal of the Transportation Research Board, 1996A testing system has been developed to study the behavior of saturated sand under low-level cyclic shearing strains. The system has been used to determine threshold shear strain levels for fabric destruction in sand aged for different time periods. The system includes a special soil chamber and a direct simple shear (DSS) machine. To impose very small

Cyclic direct simple shear testing of a Beaufort Sea clay
Canadian Geotechnical Journal, 1995Results are presented for undrained direct simple shear tests on a Beaufort Sea cohesive soil. Monotonic and one-way cyclic loading response characteristics are identified for a number of loading scenarios. The critical level of repeated loadings (CLRL) is determined for two overconsolidation ratios from tests having 30 000 cycles of loading ...

Cyclic Simple Shear Tests on Base Isolation Using Soilbags
Advanced Materials Research, 2011Soilbags have been understood to have the effect of vibration reduction and can be used as a kind of base isolation in building foundations. In this paper, a series of cyclic simple shear tests were carried out on soilbags filled with three kinds of soils under different vertical stresses to investigate the damping and stiffness characters of the ...

Testing Using a Large-Scale Cyclic Simple Shear Device
Geotechnical Testing Journal, 1986Abstract Cyclic simple shear testing is considered to be one of the most appropriate ways of reproducing in the laboratory the stresses that would be experienced by an element of soil in level ground subjected to earthquake loading. In the last few years cyclic simple shear testing has been analyzed experimentally and theoretically, and ...

Cyclic loading response of offshore pipelines using simple shear tests
Soil Dynamics and Earthquake Engineering, 2020Abstract Offshore pipelines are increasingly being adopted at elevated temperatures and pressures as more petroleum deposits are explored deep offshore. These extra-long pipelines are subjected to frequent heating and cooling cycles that can lead to ‘pipeline walking’, resulting in serviceability failures during service life.

Experimental Database of Cyclic Simple Shear Tests under Transient Loadings
Earthquake Spectra, 2017This paper describes four data sets of cyclic simple shear (CSS) tests under modulated harmonic and transient loadings. The CSS tests were performed on reconstituted Nevada Sand specimens prepared by the wet sedimentation method at target relative densities of 40% and 70%.

An Automated Control System for Undrained Monotonic and Cyclic Simple Shear Tests
GeoCongress 2006, 2006A standard NGI type Direct Simple Shear (DSS) apparatus has been modified to enable the application of unidirectional simple shear monotonic and cyclic loading through an automated electro-mechanical control system. Two algorithms were implemented in a computer control software, one for constant height control during the undrained shearing phase and ...
