<name>

Is the unique name of the bracket, used when the bracket is generated. The name should start (and preferably end) in a letter and be maximum 8 characters long.

Brackets defined in this facility are automatically activated. That is, they will pop up in the menus of Component/Create/Brackets without any separate action in accordance with the specification of the attributes SYNTAX and SYMBOL below.

SYNTAX

Specifies the connection cases (syntaxes) in which the bracket may occur. The first of the given syntaxes is the default syntax, that means, if not explicitly specified by the user this syntax will be supposed in the generation of the bracket. Syntax number 8 is the "free syntax" when all bracket parameters will have to be supplied by the user.

SYMBOL

Specifies the symbol number within the symbol font number 91 which is used in the interactive picking of the bracket type when generating the bracket. If not given it is not possible to pick the bracket by a symbol of it. It is the responsibility of the customer to create an appropriate symbol for the bracket.

EDGE_3

Specifies that the bracket has three edges, that means, two arms which are connected by an "extra" connecting edge. If this option is left out the bracket is supposed to have two arms connected directly to each other.

TOE_A

Selects a certain toe instance which must have been set up with a unique name in a TOE statement and which shall be applied at the end of bracket arm A. Two different toe selections can be assigned in case of a tight connection (for example, to a profile section). The first one will be used for connection to a flat side, the second to the side of a flanged side of a profile section (see the CONNECTION statement above).

It should be Noted that for brackets in syntaxes 1 and 5 bracket arm A is always the bracket arm that is welded against the plate surface.

CON_A

Selects a certain toe connection instance with a unique name which must have been set up in a CONNECTION statement and that shall be used in the connection of bracket arm A to adjacent structural members.

If not given, the bracket arm is supposed to be free.

It may happen that even if a connection has been defined that connection is relevant only in certain connections and that in other connections the bracket arm is free.

TOE_B
CON_B

Ditto for bracket arm B.

STIFFENER

Specifies the set of stiffening rules that should be applied for this bracket. The referred stiffener set must have been defined with a unique name in a previous STIFFENER statement. If not given, the bracket will not get any stiffener. that means, condition for a bracket to get any stiffener at all is that the bracket has been set up with a stiffener definition.

FACE_PLATE

Specifies how a face plate should be positioned on the free edge of the bracket. If not given, no face plate will be set.

This option and the FLANGE option (see below) are mutually exclusive.

FLANGE

Specifies the set of flange rules that should be applied for this bracket. The referred flange set must have been defined with a unique name in a previous FLANGE statement. If not given, the bracket will not get any folded flange.

NOTCH

Specifies a default notch selection set for use in the origin corner of a bracket. The picked notch set must previously have been defined with a unique name in a NOTCH statement.

If no NOTCH option has been given the bracket cannot have any notch in this corner.

/ NOTCH=' ' (empty string) means that a notch may occur but that no default notch exists.

NOA
NOB

Ditto for notches at the end of arms A and B, respectively. May not be relevant for all toe types.

NOC

Ditto for the notch at the start of arm A for a three-edge bracket (only when the option EDGE_3 has been used).

The figure below specifies the corners where the notches may be used.

Figure 5:19. Keywords for control of corner notches.

CUTOUT

Specifies a default cutout selection rule to be used for cutouts of a bracket. The referred cutout rule must previously have been defined in one or several CUTOUT statements.

If no CUTOUT attribute is given the bracket cannot have any cutouts. For brackets with a defined CUTOUT rule the system automatically finds the penetrating profiles and selects the cutout type based on the profile type and the rule.
