Galloping stability of triangular cross-sectional bodies: A systematic approach
TL;DR: In this article, the transverse galloping stability of triangular cross-section bodies has been systematically analyzed and the results from these dynamic tests are in very good agreement with the results obtained from the static ones.
Journal ArticleDOI
Some research perspectives in galloping phenomena: critical conditions and post-critical behavior
TL;DR: In this article, a quasi-steady model of aeroelastic forces exerted by the wind on a rigid cylinder with three degree-of-freedom, two translations and a rotation in the plane of the model cross section is presented.

A parametric study of the galloping stability of two-dimensional triangular cross-section bodies
Gustavo Alonso,José Meseguer +1 more
TL;DR: In this article, the effects of cross-sectional shape and mean wind angle of incidence on the transverse galloping stability of triangular cross-section bodies has been systematically analyzed through static wind tunnel experiments.
Journal ArticleDOI
Galloping instabilities of two-dimensional triangular cross-section bodies
TL;DR: In this paper, a systematic approach for the analysis of galloping of triangular cross-section bodies is reported, where the results have been summarized in a stability map, where galloping instability zones in the angle of attack (main vertex angle plane) are identified.
Journal ArticleDOI
Misconceptions and Generalizations of the Den Hartog Galloping Criterion
TL;DR: In this article, the authors derived the correct equations for the quasi-steady aerodynamic damping coefficients for a rotated system or wind, and the differences from other variants are highlighted.

Aeroelastic Galloping of Prismatic Bodies
TL;DR: In this paper, the steady amplitude of long prismatic bodies with aerodynamically unstable cross sections in the direction normal to that of the acting steady wind is analyzed under different conditions on the basis of the quasi-steady approach which leads to the nonlinear differential equation of self-excited oscillations.
Journal ArticleDOI
Galloping Oscillations of Prismatic Structures
TL;DR: In this article, the authors show that the tendency to galloping instability from zero position decreases with increasing turbulence intensity and can vanish at intensities of 8% or so with rectangular cross sections of 2/1.

Transmission Line Vibration Due to Sleet
TL;DR: In this paper, the authors describe the most common types of vibration in transmission lines due to the action of a transverse wind are encountered most frequently at moderate wind velocities (about 5 miles per hr.) and are characterized by high frequencies (5 to 15 cycles per sec.) and small amplitudes (up to a few cable diameters).
