Hi, Guys,
I'm new comer, lucky for me to find here:)
is anyone here know where is 42t come from?
any input welcome. thanks.

What we are using is base on ABS MODU 3-2-1.9.1
Effective Flange Area
The required section modulus of members such as girders, webs, etc., supporting frames and
stiffeners is to be obtained on an effective width of plating basis in accordance with the
following criteria. The section is to include the structural member in association with an
effective width of plating not exceeding one-half the sum of spacing on each side of the
member or 33% of the unsupported span l, whichever is less. For girders and webs along hatch openings, an effective breadth of plating not exceeding one-half the spacing or 16.5% of
the unsupported span l, whichever is less, is to be used. The required section modulus of
frames and stiffeners is assumed to be provided by the stiffener and a maximum of one frame
space of the plating to which it is attached.

Which rule mentioned 42t? I know somebody choosed max. 60t considered the effective plate buckling.

Please discuss.

thank you Paul.
that was what I use for many years in china.
only because I just come down to houston, and been told for times to use 42 or 43 times of plat thickness, and don't know why.
may be come from onshore or civil?
did any one here see it in green book or API?
thank you for join:)

DNV 里有42(235/屈α?^0.5T
----应力是牛吨/毫方
有旱鸭子对板没概念,来了个秀才念半边儿.

除上面外,
腹板是75T
面板是36T

愿与楼主换表格.
:)

学习之！
好久没见过 PONTOON 和楼主了！

在一家公司的计算报告中我也见过类似的要求，一直也没弄明白，还等待高人一解！

PONTOON那哥们说的是DNV-RP-C201里的，是局部的板稳定性，但我看过的DNV屈服计算表好像有点儿不一样，随然大家都是抄来偷去的。
ABS的就更不一样了。
那位有API 2V， 谢谢你介绍一下，没见过。
再有个事，一直不好意思问同事。用SACS作半潜模型，PONTOON作成一根，能不能算稳定性，是总体还是局部，如果是，按2V吗，如果不是，是模型简单还是软件不包。随然大家都对ANSYS感兴趣，还是只想知道。谢谢了。
