The structure of grillage is the backbone of a ship ' s structures and its compressive ultimate strength is one of the main parts in the strength analysis of a ship ' s structures . so it ' s important to make a deep research into the compressive ultimate strength of the grillage structure 由于板架结构是船体结构的主要组成部分，尤其是船舶的上甲板和船底结构，它们直接关系到船体的总纵强度，所以板架结构的压缩极限强度是设计人员十分关心的。
