Parametric Vibration Response of Columns

Journal of the Engineering Mechanics Division, 1969
Existing analysis techniques for lateral column vibrations under time pendent axial loads neglect the dynamic amplification caused by these loads. Respon to one type of dynamic load is investigated, and the basic linear differential equation motion is developed. Maximum transient displacements at midspan of initially curve.

Random Vibration of a Beam Column

Journal of the Engineering Mechanics Division, 1965
The lateral displacement of a vertical cantilever beam subjected to an axial load acting at the free end and under a random horizontal motion of the clamped end is evaluated. This is one of the beam-column problems on which little work has been done for random loading on random boundary conditions.

Vibrations of a gas column

Physica, 1949
Abstract It has often been observed, in particular in low-temperature experiments, that spontaneous vibrations may occur in gas columns if the temperature of the tube containing the column varies markedly along its length. An explanation of this phenomenon was recently suggested by Mr T a c o n i s.

Mitigation of Wind-Induced Vibration with Liquid Column Vibration Absorber

Advances in Science and Technology, 2008
Increasing heights of tall buildings often require supplementary damping system for occupant comfort in windy condition. This paper presents a liquid column vibration absorber (LCVA) installed in a 64-story building, which is the highest residential building with flat plate structural system in Korea, for mitigation of wind-induced motion.

Intensification of Slurry Bubble Columns by Vibration Excitement

The Canadian Journal of Chemical Engineering, 2003
AbstractWe show that application of low‐frequency vibrations, in the 30 to 60 Hz range, to the liquid phase of an air — water — silica catalyst slurry bubble column causes significant enhancement of both gas holdup and volumetric mass transfer coefficient over a wide range of superficial gas velocities.

Estimation of Vibration Response of a Bridge Column

SSRN Electronic Journal, 2019
Moving vehicle on a bridge is considered as a moving load and the bridge structure is considered as a continuous beam. Due to the moving position of a vehicle on the bridge, the reaction on each column may be changed. This reaction is time variant for each column. The time-variant reaction is the major accountable factor in the generation of vibrations

Power dissipation in a vibrating disc column

The Chemical Engineering Journal, 1979
Abstract The power dissipation in a vibrating disc column of 17.2 cm inside diameter has been measured in a liquid single-phase system and in a gas—liquid two-phase system. For frequencies less than 5 Hz, the power dissipation in the column is mainly controlled by the maximum drag force exerted on the vibrating disc at the maximum velocity of disc ...

A note on vibration of beam-columns

Journal of Sound and Vibration, 1986
Abstract Eigenfrequencies for beam-columns with flexible supports are determined by a unified equation which includes all classical, idealized boundary conditions as special cases. For the approximation of linear dependence between squared eigenfrequency and column load, good agreement is found when the supports are translationally fixed, but slight ...

Free Vibration of Stochastic Beam-Column

Journal of the Engineering Mechanics Division, 1971
The mean and variance of n th natural frequency of a beam-column are obtained by a perturbation method when the material and geometric properties, the axial load, and the boundary conditions are probabilistic. The realtive effects of uncertainty in input parameters such as axial load and structural properties with uncertainty in output parameters of ...

Vibration of a Segmented Heavy Column

Journal of Vibration and Acoustics, 2010
The vibration of a standing (or hanging) segmented column, affected by its own weight, is studied. The governing difference equations are solved numerically. The results tend to those of the continuous column as the number of segments tends to infinity.
