Calibration and limitations of a fixed-partly fixed resonant column apparatus [PDF]

E3S Web of Conferences
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 apparatus’s active end.

Macroscale signatures of crushing from resonant column tests [PDF]

EPJ Web of Conferences
The resonant column apparatus has been widely used to measure the dynamic properties of particulate geomaterials, and to describe their variation as a function of confining stress and strain.

Laboratory Characterization of a Compacted–Unsaturated Silty Sand with Special Attention to Dynamic Behavior

Applied Sciences, 2020
The dynamic properties of compacted non-cohesive soils are desired not only because of the risk of natural sources of dynamic excitations such as earthquakes, but mostly because of the anthropogenic impact of machines that are working on such soils ...

Low-amplitude dynamic tests of fine gravel in a resonant column [PDF]

E3S Web of Conferences, 2019
Construction of industrial and civil buildings, taking into account the dynamic effects on the foundations, requires special experiments on the mechanical properties of soils. This article presents the results of studying the dynamic properties of coarse

The New Empirical Equation Describing Damping Phenomenon in Dynamically Loaded Subgrade Cohesive Soils

Applied Sciences, 2019
The damping ratio (D) is one of the key soil parameters in geotechnical issues where the soil is subjected to dynamic loads, like machines foundation, city tram and subway traffic, and driving of sheet pile or precast pile.

Results of the Study of Resonant Oscillations in the Northern Part of the Shelf of the Peter the Great Gulf, the Sea of Japan

Journal of Marine Science and Engineering, 2023
To study the features of resonant oscillations in the water column of the Peter the Great Gulf of the Sea of Japan, in situ measurements were carried out on its shelf, combined with numerical simulation of these processes.

MODELING OF RESONANCE EFFECTS IN SPINE WITH ADDITIONAL FIXING ELEMENTS [PDF]

Научно-технический вестник информационных технологий, механики и оптики, 2019
Subject of Research. We study the procedure of natural frequencies calculation for a system consisting of a human spine with fixing elements. Resonant effects can occur in the vicinity of such system leading to stability violation or structure ...

Timoshenko beam effect in flexural resonant column tests

, 2018
Current methods for deriving Young's modulus (E) from flexural resonant column tests do not account for the Timoshenko beam effect. Hence, the extent of the Timoshenko beam effect is investigated in this study using a series of numerical experiments ...
