General

Once the Reinforcement Pattern command is called up and the 'General' tab is selected, a dialog box shown below will appear on the screen.

In the above dialog box, the user may set the general parameters pertaining to the entire beam. These include:

Note: The Break in concreting option is provided in the above dialog box only when the French code of RC structure design (BAEL91) is selected.

In the lower part of the dialog box there is the Bent bars option. If the option Bent bottom bars or Bent top bars is switched on, then bent bars may be used during calculations of the beam reinforcement. Bent bars will be generated only then if a number of reinforcement layers is greater than one and at least one of the reinforcement layers ends within the span.

The following parameters of bar bends need to be determined:

If the Consider slab parts of T-section in quantity survey option is switched on, then the volume of concrete necessary to make a beam will be calculated for the T-section of an RC beam; if this option is switched off, the concrete volume will be calculated for the rectangular cross section of an RC beam.

If the Ignore verification of reinforcement shape during structure verification option is switched on, then the code requirements concerning diameters, stirrup shapes, bend angles, etc. will not be checked. This option is used to accelerate structure calculations.

An additional useful option in reinforcement management within the layer is Anchorage. Clicking the Anchorage button allows to open the dialog where the anchorage parameters can be defined.

The Consider hook length in anchorage length option refers to ribbed bars (i.e. such ones for which hooks are used optionally), bent at the right angle and anchored in the support.

If the Anchor loops at beam ends option is switched on, then the additional reinforcement in the shape of loops will be generated on the ends of a beam according to choosen option:

With it, the user defines the manner in which span reinforcement reaching supports must be anchored. Generation of the anchorage may be defined based on the kind of support with differentiation into edge and middle supports left and right of the span in question. The Auto option selects the bar length in the support area that meets the reinforcement anchorage conditions. The remaining three anchorage options: Crossed, Not crossed and Stopped act by forcing a cut (bar end in the support area is a value that depends on the c cover). In the case of selecting one of these three options as well as insufficient anchorage length, the program warns the user displaying an appropriate warning. The c parameter that may be defined in the top part of the Span Reinforcement Anchorages dialog box allow controlling the length of anchorages when one of the following anchorage types is selected: Crossed, Not crossed and Stopped. When the Cage method option is chosen, the reinforcement is adjusted to the successive spans in such a manner that it does not clash with the column reinforcement, and afterwards, the reinforcement is made continuous over the supports by means of additional bars.
