Fatigue Tests of A441-A36 Hybrid Plate Girders

This paper presents the results of an investigation intended to obtain fatigue data for hybrid plate girders and to determine their fatigue strength at two million cycles. Fatigue tests were conducted on six welded hybrid plate girders with flanges of A441 steel and webs of A36 steel. Web slenderness ratios of 144 and 192 were investigated. A sequential test programme was devised to determine the maximum permissible stress range that will give a life of two million cycles. A. Anthony Toprac and David J. Fielding
