Creates a circular reinforcement element

Single reinforcement bars are generated along a defined cicular or cicular arc.

To use this command of the circular reinforcement, at first it is necessary to create a circle or an arc with the drawing commands of AutoCAD.

Three possibilities are available for the input the reinforcement values:

• Definition of the number of bars

  The minimum reinforcement is determined automatically using the diameter and the number. The maximum reinforcement can be defined as total reinforcement area, e.g. in [cm²].

• Definition of the minimum and maximum reinforcement as total reinforcement area, e.g. in [cm²]

• Definition of the minimum and maximum reinforcement with the grade of reinforcements, e.g. in [cm²/m]

After the definition of the reinforcement values only the command ‘Pick circle or arc’ is available. When clicking on the circle or arc, the circular reinforcement element is generated automatically. Additionally the centre of the circle and radius are shown. They can be referenced and get a variable in order to make the definion of a parametric cross section.

During calculation single reinforcement bars are generated using the input for diameter, distance, reinforcement and maximum reinforcement. With ‘Distribution of bars’ several possibilities are available for the distribution of the single bars.

A detailed description of these properties can be found in the chapter ‘CRF - Circular Reinforcement’ of the manual AQUA.

An explanation about the use of the layers is available in the manual AQUA in chapter ‘LAY - Reinforcement Layers’, in the subchapter ‘Properties of reinforcement elements’ and in the manual AQB in chapter ‘Theoretical Principles’.

The specification for the torsional efficiency controls whether the reinforcement is taken into account in the calculation of torsional stresses.

For special cases a reference area (simplified influence area of the bars to the surrounding concrete) can be defined for the determination of the crack width.

Available options:

For creation of circular reinforcement, the following option is to be used automatically:

Pick Circle or Arc

Creates an element of a circular reinforcement. This command is used automatically for the definition of a circular reinforcement.
