Dynamic Properties of Clean Sand and Expansive Clay from Resonant Column Studies [PDF]

, 2015
Design of structures subjected to different dynamic loads requires the dynamic properties of soil. The dynamic load may come from earthquakes, pile driving operations, vibrations from machines, ocean waves, blasting operations etc.

On determining the elastic modulus of a cylindrical sample subjected to flexural excitation in a resonant column apparatus

, 2010
For resonant column tests conducted in the flexure mode of excitation, a new methodology has been proposed to find the elastic modulus and associated axial strain of a cylindrical sample.

Multi-Modal Synthesis and Variable Modulus Effects in Resonant Column Tests by Random Excitations

, 2010
To extend current measurement and data synthesis techniques for resonant column testing, random vibration transfer functions measured using a modified 6 inch (152.4 mm) diameter Drnevich free-free resonant column device are evaluated against viscoelastic

Calibration and Limitations of a Fixed-Partly Fixed Resonant Column Apparatus

, 2023
The small-strain shear modulus of soils and rocks is an important input parameter in geotechnical analyses. Its estimation using the resonant column apparatus relies on accurate knowledge of the rotational inertia of the apparatuss active end. Due to the

Design Considerations of the Resonant Chamber of an Oscillating Water

Revista UIS Ingenierías
One of the most promising devices for harnessing the energy of the waves is the oscillating water column (OWC). Since its creation, it has been evidenced that this device has been a subject of multiple investigations focused on improving its ...

Assessing Cross anisotropy of Small-Strain Stiffness Using the Resonant Column apparatus

, 2010
Almost all soils exhibit cross-anisotropic stiffness to some extent. However, measuring the cross anisotropic properties of soils is difficult because of the need to determine the 3 independent stiffness parameters Eν, Eh, Gνh, and the associated Poisson’

Energy-injecting virtual mass resonant column system

, 1998
An innovative resonant column control system is introduced. The system is based on the concepts of energy injection and virtual mass. A unique feature of the system is that it allows the user to specify the resonant frequency and vibrating amplitude for ...

Evaluation of ground densification using spectral analysis of surface waves (SASW) and resonant column (RC) tests

, 1999
In order to assess the quality and depth of ground densification due to compaction, standard and (or) cone penetration tests are often performed before and after compaction.

Effect of Loading Frequency on Dynamic Properties of Soils Using Resonant Column [PDF]

, 2012
Dynamic properties of soils (shear stiffness and damping ratio) are critical for the design of structures subjected to vibrations. The dynamic properties of a benchmark standardized laboratory sand (Ottawa silica sand) were evaluated with two different ...
