Wire fabrics in cross section - wire fabric shape

Use this option to define the wire fabric in a cross section (of a wire fabric shape) of an RC structure element. There are several ways to access this option:

• Menu: Reinforcement > Wire fabrics in cross section
• Ribbon: ASD - Reinforcement > Reinforcement - definition > Wire fabrics in cross section
• Toolbar: Definition - wire fabrics > Wire fabrics in cross section
• Command line: RBCR_DEF_NET_SIDE.

After selecting the Wire fabrics in cross section option, the following dialog displays:

The Wire Fabric Shape dialog is be divided into three parts:

• The left-hand side of the dialog contains basic information about a wire fabric: wire fabric type, cover and reinforcing steel grade adopted from the settings in the preferences
• The center of the dialog provides options used to define the geometrical parameters of a wire fabric
• The right-hand side of the dialog includes icons that are used to select a mode of graphic definition of a wire fabric; Note: wire fabrics may be defined only after selecting these icons.

The dialog displays the last-defined type of a wire fabric and parameters adopted for it.

The icon is used to assume parameters of the earlier-defined wire fabric.

To define a wire fabric in the cross section, it is necessary to specify the following parameters in the dialog:

• Wire fabric type (by default, the last type defined is adopted)
• Wire fabric cover (by default, the last cover defined is adopted)
• Reinforcing steel grade
• Bent wire fabric side - a longer (L-main direction) or a shorter (l) edge of the wire fabric panel will be bent
• In the Shape parameters field - parameters of the hook ending of a wire fabric, i.e. a hook angle and length (the hook length defined in the dialog box is a length of the straight segment of the hook).

The list of standard values (see: the method of measuring the angle of bar bending) of hook angles include:

• 0°
• 90°
• 135°
• 180°
• -90°
• -135°
• -180°.

While defining a wire fabric shape in the cross section, the following icons are available:

Points - click to define the points that determine the wire fabric shape

Select - click to select an object (line, polyline, arc, etc.) whose shape will determine the wire fabric shape.

Note: Wire fabric location depends on the direction of point definition. The rule that holds while defining a wire fabric is identical as in definition of a reinforcing bar: determining the order of points clockwise (along the EXTERNAL part of an object).

Once definition of a reinforcement shape is complete, the Reinforcement description dialog, used to select elements of reinforcement description, displays.
