LR V.1.2 General definitions and symbols
LR V.1.2.1
The following symbols, used in these Rules, are fully defined
in Pt 3, Ch 1, 6 Definitions*:
L
|
= |
length
of ship, in metres |
B
|
= |
moulded
breadth of ship, in metres |
D
|
= |
moulded
depth of ship, in metres |
T
|
= |
moulded
draught of ship, in metres. |
LR V.1.2.2
The following symbols are also used in this Chapter. Where these
symbols are used in a different or more limited sense, with or without
a distinguishing subscript, the amended definition is given at the
head of the Section concerned.
h
|
= |
the
load height applied to the item under consideration, in metres |
I
|
= |
the
moment of inertia, in cm4, of a primary or secondary member
in association with an effective width of attached plating, determined
in accordance with Pt 3, Ch 3, 3 Structural idealisation*
|
L
1
|
= |
length of ship, in metres, but need not be taken greater than
190 m |
p
v
|
= |
pressure/vacuum relief valve positive setting, not to be taken
less than 0,2 bar gauge |
S
|
= |
span,
in metres, of the primary or secondary member measured between effective
span points. For the determination of span points, see
Pt 3, Ch 3, 3 Structural idealisation*
|
s
|
= |
spacing
of secondary members, in mm |
t
|
= |
thickness
of plating, in mm |
z
|
= |
the
section modulus, in cm3 of the primary or secondary member,
in association with an effective width of attached plating determined
in accordance with Pt 3, Ch 3, 3 Structural idealisation*
|
Z
B
|
= |
actual hull section modulus at the keel, in cm3,
as determined in accordance with Pt 3, Ch 3, 3 Structural idealisation*
|
Z
R
|
= |
Rule hull section modulus, in cm3, as determined
from Pt 3, Ch 4, 5 Hull bending strength*
|
ρ |
= |
relative density
of cargo, but not to be taken less than 1,025 |
LR V.1.2.3
The expression ‘primary member’ as used in this
Chapter is defined as a girder, transverse, vertical web, stringer,
cross tie, buttress or double bottom floor. ‘Secondary members’
are supporting members other than primary members.
