| 摘 要： | 大跨空间结构在风等交变荷载作用下,结构的应力循环交替变化,可能形成结构的疲劳损伤。通过对2008奥运羽毛球馆采用总寿命法进行疲劳分析,结合疲劳分析的基本理论,运用雨流计数法,统计出了应力循环历程,采用Miner线性累积损伤理论,得到了结构在荷载过后的疲劳损伤程度,找到了疲劳危险区域,得出了一些结论。 |
| 关 键 词： | 脉动风荷载 AR模型 疲劳损伤 |

| Abstract: | Under wind loads, the cycle alternative variation of structural stress may lead to brittle fatigue failure of long-span spatial structure. The paper adopt total life method to carry out the fatigue analysis on 2008 Olympic Badminton Gymnasium, apply rainflow counting method to count the strain cycle history. The degree of fatigue damage is got by Miner linear accumulated damage theory, and then dangerous areas caused by fatigue can be found and some reasonable conclusions are acquired. |
| Keywords: | fluctuating wind load AR model fatigue damage |
