Syntax 3

The images below illustrate different situations in which a bracket can be generated according to syntax 3.
In the images, LIM means a limit, F a flange, L a shell profile and S a stiffener on an adjacent panel.

Except for a connection with a three-arm bracket, any of the involved panels can be the current one.

<syntax_3>::= [,A= <length_A>]
<F_ref>
|
|
|
A |
The length of arm A. Must always be give for two-arm brackets If A=<a> (<10) then A=<a>*B. For three-arm brackets A will be calculated from B as described in syntax 2 above (or from depth). |
|
B |
The length of arm B. If B=<b> (<10) then B=<b>*A. If B is not given for a two-arm bracket it will be set equal to A. If B is not given for a three-arm bracket it will be calculated from A as described in syntax 2 above (or from depth). |
|
K |
See Syntax 2. |
|
The definition of the position of the bracket arms is done in the following way:
|
|
|
SI2 |
Defines the position of the bracket relative to the limit before the first slash. Not relevant for profile and limit references and never for three-arm brackets. When given together with a line it makes the direction of the line irrelevant. <side_info>, see SIDE, Common Syntax |
|
Regarding <line>, <line_1>, <line_2>, <ext_prof_ref>, <F_ref>, see General Layout of a Statement. |

|
<panel>::= <curve>::= <name> |
|
|
<lim_no>::= <integer> |

Examples:
Bracket KC belonging to a deck web.
|
BRA, KC, COR=2, PSIDE=AFT, DOUBLE, A=2600, MAT=15, 'AA465-7', F1/F1; |
Bracket B, one arm of which is defined by a line.
Note: The bracket will lie to the left of the line.
|
BRA, B, COR=2, SYNT=3, MAT=15, PSIDE=TOP, A=500, U=23200, T=270/LIM=4; |
A bracket BR connecting a double floor bottom to a transversal.
|
BRA, BR, MAT=12, A=500, TR75/LIM=2; |
A bracket along a limit with arm B restricted by a panel surface.
|
BRA, KL, MAT=12, A=700, ‘AB123-4’, SI2=PS/ LIM=3, ... ; |
