摘 要: | 针对两种损伤模式,建立基于过载法的船舶板架结构冗余度计算模型,推导板架结构连续垮塌的最大屈曲利用因子计算公式。计算了6艘CSR船舶船底、内底板、舷侧板和甲板等板架损伤态的屈曲利用因子,验证船舶板架的冗余度。

Research about structural redundancy of grillage stiffener based on over load method |

Abstract: | For two damage assumption conditions, the computational model for the structural redundancy of a ship grillage stiffener is developed. A formula for maximum buckling utilization factor is derived, which is applicable for progressive collapse of ship structure grillage stiffener. The calculation results of 6 actual bulk carriers and oil tankers designed by CSR-H show that the actual ships satisfy the evaluation criteria of structural redundancy. |
