Effect of Re-vibration Process on Axial Capacity of Short Reinforced Concrete Circular Columns [PDF]
A considerable amount of research work has been performed on the effects of vibrating of fresh concrete on the reduction of shrinkage and creep, the improvement bond stress between reinforcing bar and concrete, reduction the concrete permeability and ...

Improving seismic resistance using absorbing nodes [PDF]
A flexible gusset is a device that improves the seismic resistance and energy dissipation capacity of a structure. To achieve these solo vibration characteristics, the flexible gusset is designed to remain elastic, resulting in reduced vibration to the ...

Vibration Damping in Bolted Friction Beam-Columns [PDF]
In this paper we consider dynamic friction within a bolted structure deliberately used to improve damping properties of engineering structures. The model considered for this paper consists of two steel beam-columns bolted together allowing dynamic friction to occur at the interface.

Interstitial gas effect on vibrated granular columns [PDF]
Vibrated granular materials have been intensively used to investigate particle segregation, convection, and heaping. We report on the behavior of a column of heavy grains bouncing on an oscillating solid surface. Measurements indicate that, for weak effects of the interstitial gas, the temporal variations of the pressure at the base of the column are ...

Simulation of Inhomogeneous Columns of Beads under Vertical Vibration [PDF]
We present results from computational experiments of one‐dimensional inhomogeneous granular column. With characteristic properties lying between those of liquids and solids, this class of material consists of assemblies of solid particles which interact via mechanical forces (contact and friction) and are maintained together by a gravitational field ...

Vertical vibration is known to cause bubble breakup, clustering and retardation in gas-liquid systems. In a bubble column, vibration increases the mass transfer ratio by increasing the residence time and phase interfacial area through introducing kinetic
