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(jié)構(gòu)是船體結(jié)構(gòu)的主要組成部分,尤其是船舶的上甲板和船底結(jié)構(gòu),它們直接關(guān)系到船體的總縱強(qiáng)度,所以板架結(jié)構(gòu)的壓縮極限強(qiáng)度是設(shè)計(jì)人員十分關(guān)心的。
