A reinforcing apparatus for supporting a utility pole against the bending forces of transverse wind components is described. The apparatus comprises an intermediate section extending to and meeting with spaced apart flanges. The intermediate section and the flanges are configured such that the elastic axis and shear center of the reinforcing apparatus is closer to the longitudinal axis of the pole and the point of load transfer from the pole than realized by prior art reinforcing apparatus. The intermediate section may have a variety of shapes, such as a "U" shape, "V" shape, or channel shape. The reinforcing apparatus may be constructed of high yield strength steel and is secured to the pole by means of one or more bands, or by means of bolts, screws or other fastening means.
Dispositif de renforcement pour soutenir un poteau de ligne contre les moments de flexion exercés par des vents de travers. Le dispositif comprend une section intermédiaire se prolongeant jusqu'aux semelles espacées et les rencontrant. La section intermédiaire et les semelles sont configurées de façon que l'axe d'élasticité et le centre de cisaillement du dispositif soient plus près de l'axe longitudinal du poteau et du point de transfert de la charge du poteau que dans le dispositif classique. La section intermédiaire peut prendre plusieurs formes : en U, en V ou en profilé. Le dispositif peut être fait en acier à haute limite élastique et est fixé au poteau par un ou plusieurs feuillards, ou par des boulons, des vis ou d'autres dispositifs de fixation.
