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 由于板架結構是船體結構的主要組成部分,尤其是船舶的上甲板和船底結構,它們直接關系到船體的總縱強度,所以板架結構的壓縮極限強度是設計人員十分關心的。
