The images below illustrate the type of connections which the brackets may be part of. (In the images, L denotes shell profiles, S stiffeners and F flanges.)

Typical bracket arrangements in syntax 2:

3-edge bracket in syntax 2:

Any of the involved panels can be the current panel.

In case of a 3-edge bracket the references must be given in the order A / B / C. The name of the current panel may be left out. In this case it does not make sense to mirror the bracket. (Brackets with these edges must have been established by the customer in the Extended Bracket Handling.

<syntax_2>::=

      [,A= <length_A>]
      [,K= <depth>]
      [,B= <length_B>]
      [,SI2= <side_info>]
      [,OFF=<offset>]
      [,<bkt_dir>]

[/ <prof_ref> (1 ... 25), [REF]]
[/ <name>[<int_prof_ref> (1 ... 25), [REF]]

For <prof_ref>, see General Layout of a Statement.

<pan_ref>	is used when the adjoining panel is the panel with the plate surface for 2-edge brackets.
	<pan_ref>::= <name>
SID	(See Common Input for Syntaxes 1 to 7) should always be given relative to the plate surface (that means, not necessarily relative to the current panel).
A	defines the length of the side A of the bracket.
A	<length_A>::= <number>
B	Ditto for side B. If not given, B is supposed to be equal to A.
	<length_B>::= <number>
	In the case of a 3-edge bracket A and B may be calculated from each other to ensure the same distance of the bracket toes from the intersecting plane, see the image below.
	Default rules for A and B in 3-edge brackets: Assigning any of A or B a negative value means that the distance (height) shall be measured perpendicularly to the bottom of the bracket.
<length>	As an alternative to giving A (and B) in case of 3-arms brackets with its free side parallel to the base of the bracket K can be assigned the depth of the bracket (See 3-arm brackets controlled by Depth).
SI2	If a bracket is set at the edge of a flange, it is necessary to select one of the possible edges (see the images above). The same is true if a stiffener is referred to by a tag reference and there are stiffeners on both sides of the panel. <side_info>, see SID, Common Syntax. If SI2 is not given in a connection to a flange, the bracket will be connected to the flat side of the flange.
OFF	See General.
<bkt_dir>	See General.

Examples:

A BAK-bracket connecting a bottom web to a longitudinal.

BRA, BAK, COR=3, SYN=2, MAT=12, SID=FOR,
PSIDE=SB, A=845, B=1000, L290;

A KL-bracket connecting a longitudinal bulkhead to the flange of a web, and belonging to the bulkhead.

BRA, KL, SYN=2, SID=SB, SI2=FOR, A=600,
PSID=BOT, MAT=12, 'AA141-3', F1;

A user defined 3-edge bracket, connected to the plane of the current panel.

BRA, ABC, NOT=R50, NOC=R50, MAT=10, B=500, SID=TOP
/'AA123-4', SL45,
/TR45;

Since A has been left out it will be set B/sin(V).
