Dynamic of a cylindrical column on a vibrating base [PDF]
Vibroengineering Procedia, 2021 The solution of the problem of cylindrical column on a rigid horizontal foundation motion is presented. It is assumed that the base moves in a horizontal direction, there is no slippage between the column and the base, and the column height is significantly greater than the base diameter.

Study on Fluid-Induced Vibration Power Harvesting of Square Columns under Different Attack Angles
Geofluids, 2017 A model of the flow-vibration-electrical circuit multiphysical coupling system for solving square column vortex-induced vibration piezoelectric energy harvesting (VIVPEH) is proposed in this paper. The quasi steady state theory is adopted to describe the

Stability and Vibration of Imperfect Column
Procedia Engineering, 2012 AbstractA special problem of the frequency of the column loaded in compression is presented. In the case of the linearised stability and if the force is close to the elastic critical load, the natural frequency limits to zero. Taking into account the nonlinear theory and the real boundary conditions and for the force near the elastic critical load, the

Vibrational Collapse of Hexapod Packings
EPJ Web of Conferences, 2017 Columns made of convex noncohesive grains like sand collapse after being released from a confining container. However, structures built from non-convex grains can be stable without external support.

Method Improvements of Testing Modulus of Soil Based on Free-Vibration Column
Advances in Civil Engineering, 2019 It is difficult to directly measure the dynamic elastic modulus of soils when the strain is less than 10−4, though the dynamic shear modulus can be easily obtained by the free-vibration testing method.
