| 摘 要： | 抖振是桥梁在风荷载作用下的一种经常性的限幅振动。对于长大跨度桥梁在计算其抖振响应时不得不考虑自激力的影响，而自激力的计算方法不一，且其计算过程复杂，繁琐。本文根据抖振计算理论，研究一种自激力的实用计算方法，并对军山斜拉桥进行自激力计算。

| Abstract: | Buffeting is the usual random vibration with the amplitude limited under natural wind. Self-excited force must be considered when calculating response of long-span bridge buffeting. The authors worked out a practical calculating method of self-excited force according to buffeting calculating theory and calculated self-excited force of Junshan cable-stayed bridge. |

| Keywords: | buffeting vibration self-excited force transfer function |
