| 摘 要： | 建立了船舶结构板架扶强材连续垮塌的计算模型，推导船舶结构板架扶强材连续垮塌的最大屈曲利用因子公式。以某油船为例，在两种损伤模型作用下，计算出船底、内底板、舷侧板和甲板等处的屈曲利用因子，验证板架扶强材的连续垮塌。

| 关 键 词： | 扶强材 屈曲利用因子 垮塌 |

| Abstract: | This paper builds a computational model for the progressive collapse of the ship structure grillage stiffener, and derives a formula of its maximum buckling utilization factor. Taking a tanker as an example, it calculates the buckling utilization factors of bottom, inner bottom, side shell and deck under the two damage models which veriifes the progressive collapse of grillage stiffener. |
