Arc-shaped reinforcement

After selecting the arc-shaped reinforcement, the Special reinforcement dialog displays:

To define a bar, specify the following:

• Bar diameter (the diameter defined in the dialog is adopted by default)
• Reinforcing bar cover (the cover defined in the dialog is adopted by default)
• In the Shape parameters field - anchorage parameters for reinforcing bar ends, i.e. hook angle and length; you can lock a hook length by selecting the option next to the edit field for defining a hook length ( appears). The edit field becomes inaccessible. If you modify parameters (length or diameter) of a bar with locked hook length, the hook length does not change.

While defining the arc-shaped reinforcement, the following icons are available:

• Start-Center-End - is used to define an arc by specifying three snap points of the arc: arc beginning point, arc center and arc end point. After selecting any point, the dialog closes, and as the cursor is moved, the reinforcement is presented dynamically

  Command line:

  Select start point

  Select arc center

  Select arc end

  or

  Select arc center

  Select arc start

  Select arc end or [Angle / Arc length]

  where:

  start point - arc beginning

  arc end - end point

  arc center - point being arc center

  angle - value of arc angle

  length - value of arc length

  
• 3 Points - the function which enables arc definition by specifying three points belonging to the arc. The dialog box closes; while moving with the cursor the reinforcement being defined is presented dynamically

  Command line:

  Select first point

  Select second point

  Select third point

  where:

  first, second and third points denote successive points belonging to an arc

  
• Select - is used to indicate directly an arc-shaped object. After selecting, the dialog closes, and the cursor assumes the shape of a square (see the ACAD command 'copy' - the stage of selecting an object for copying). Once any element is selected, an ACAD object is detected on the screen and reinforcement is drawn within the indicated object.

  Command line:

  Select object

  Side

  1 Hook

  2 Hook

  where:

  object -arc or polyline segment

  side - modifies reinforcement position with respect to an object (formwork)

  1 hook - direction of hook bend

  2 hook - direction of hook bend (opposite in relation to hook 1)
