研究了斜拉索风致振动的疲劳损伤问题。首先，根据 Miner 线性累积损伤原理，给出了结构疲劳损伤的计算公式。其次，根据高周疲劳的特性，我们假设斜拉索的疲劳损伤符合 Basquin 疲劳估算模型。第三，在综合目前疲劳损伤既有研究的基础上，进一步提出评价不同风速和不同风攻角对斜拉索疲劳损伤影响的框架。最后，以松花江斜拉桥中的斜拉索为对象，基于动力时程法计算分析了在不同风速和不同风攻角情况下斜拉索上各节点的应力时程，再使用雨流计数法统计斜拉索的应力-应变循环历史，估算出在不同风速和不同风攻角下斜拉索的疲劳损伤。于是，定量地评价了在不同风速和不同风攻角对斜拉索疲劳损伤的影响。

The main objective of the present paper is to analyze the wind-induced fatigue damage of inclined cables. Firstly, following the liner accumulated damage theory proposed by Miner, the computational formula of structural fatigue damage is suggested. Subsequently, according to the high-cycle fatigue damage properties, it is hypothesized that the fatigue damage of inclined cable obeys with the Basquin fatigue estimate model. Thirdly, on the basis of the present researches, the framework is proposed for the influences of different wind speeds and different wind attack angles on the fatigue damage of inclined cable. Finally, taking the inclined cable in Song Hua Jiang Cable-stayed Bridge as an example, the time history stress of several positions in the cable under different wind speeds and different wind attack angles is calculated and then, the stress-strain cycle history of the inclined cable is obtained by resorting to the rain flow digit method, thus examining the influences of different wind speeds and different wind attack angles on the fatigue damage of inclined cable.
