大开口船舶板架的稳定性分析及补强方法研究

利用理论分析方法对大开口船舶板架结构的开口区域纵向构件受力状况和开口边缘筋条侧倾稳定性进行了分析和计算 ;对于大开口船舶板架中影响其稳定性的结构因素进行了研究 ,提出了在压缩载荷下大开口板架的补强方法。选取了一个典型船舶板架结构对于开口和未开口板架进行了稳定性计算 ,最后计算了经过补强的板架结构 。

Theoretical method was used for analysis and calculation of large hatch ship panel structure's girder in the hatch area and stiffener's side direction stability; the structural factor influenced stability of panel was investigated, and the strengthen method under compress load was represented. A typical ship panel was selected to calculate the stability of panel with and without large hatch; a strengthened panel was calculated at last, the strengthen method represented by this paper was proved to be very effective.
