Abstract

A nondestructive vibratory testing using impulsive tension slacking has been devised for the quality and safety control of overhead line towers of Electricité de France. Several structural control experiments have been conducted on four-legged towers resting on three types of foundations: concrete stepped or pedestal blocks, steel piles and prestressed foundations. Experimental results have given significant vibratory signatures in close connection with the geotechnical response characteristics of both slender structures and their foundations. This paper presents some significant results of the test program of safety evaluation of the pylon.
