Özet
In this study, a new cycle counting method is developed to determine the number and amplitude of large and small displacement/strain cycles. A new equation is obtained to determine a displacement/strain cycle amplitude representative of a number of small amplitude cycles existing in a typical temperature induced displacement/strain history in steel H-piles of integral bridges. The effect of primary and secondary small cycles are investigated for different integral bridges
