Vertical loop

After selecting 'vertical loop' reinforcement (used in retaining walls or tanks), the Special reinforcement dialog displays:

To define a bar, the following should be specified:

• 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 this reinforcement type, only one icon (Points) is available in the dialog. After selecting it, the dialog closes, and the cursor assumes the shape of a cross (see the ACAD command 'line'). During reinforcement definition, you should specify three snap points of this reinforcement type.

Note: Once definition of this reinforcement type is completed, reinforcing bar parameters can be modified (in particular, a radius of bar bend) by means of the options provided in the Reinforcement -> Modify menu (a radius of bar bend can be changed by activating the Reinforcement -> Modify -> Bent diameters option).

Command line:

Select bar attachment point

Select second bar point

Select bar node

Cover / Side / Mirror

where:

first (attachment point), second and third point as shown in the drawing

cover - determines a cover value for each segment of reinforcement separately

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

mirror - mirror reflection of the defined reinforcement with respect to the first segment of reinforcement
