In designing of tubular steel trussed towers, fatigue performance against wind loads needs to be evaluated. Here, a fatigue design method is proposed together with its design conditions. To this end, fatigue tests were carried out and the resultant stresses and strains around fatigue cracks were evaluated. As results: (i) no influence on the number of load repetitions for cracks and failures is recognized after removing residual stresses during galvanizing or annealing, (ii) fatigue performance within the hot spot strain is found to be equivalent to that by load amplitude for yield strength and thus, its application to tubular members stiffened by ring-stiffeners is practically possible.
