摘要
文章以单层板架、开孔单层板架和双层板架为研究对象,采用非线性有限元法,开展了端面转角对板架结构极限强度的影响研究。首先对单层板架、开孔单层板架和双层板架在不同端面转角下的极限强度进行了系列数值计算,然后对比分析其极限载荷和失效模式,获得了端面转角对板架结构极限强度的影响规律,为开展甲板板架结构极限强度试验提供方法参考。
This paper takes single grillage,single grillage with opening and double grillage as research objects,and conducts some researches on the influence of rotation of end face on the ultimate strength of grillage structure with nonlinear finite element method.First,a series of numerical calculations about their ultimate strength at different rotation of end face are carried out.Then the influence rule of rotation of end face for ultimate strength of grillage structure will be obtained by comparative analysis of limit load and failure mode.This studied result could provide method reference for the ultimate strength test of deck grillage.
