Rebar Check#

Allows comparison of drawn reinforcement with design results for slabs, columns and beams. The check can be visualised with point- or cutline-based Display Styles. The Rebar Check is meant to gain a quick, rough overview about the required and provided reinforcement. The conscientious inspection of the reinforcement for structural and static details remains the user’s responsibility.

General#

Select within the SOFiSTiK: Rebar Check panel desired results by picking Data source resp. Design case. Display pattern contains default visualisation styles, the further options give possibility to configure the view in more detail. With Reload all results and cutline diagrams get refreshed.

Rebar Check: Slabs#

The point-based Rebar Check colorizes calculated results according to the chosen evaluation type on slabs. The major direction of the reinforcement must be aligned with the span direction of the corresponding analytical panel.

Further information about anchoring factor

Anchoring factor is used to determine overlapping and supplementary reinforcement. It corresponds to the basic required anchorage length lb,rqd in relation to the diameter. The default value 45 is derived from C20/25 concrete in good bonding:

\[l_{b,rqd} = Anchoring factor * \varnothing = \frac{1}{4} * \frac{ \sigma_{sd}}{f_{bd}} * \varnothing = \frac{1}{4} * \frac{435N/mm^{2}}{2,32N/mm^{2}} * \varnothing = ~45 * \varnothing\]

The main concept to identify the role of reinforcement relies on dividing it into three segments: Left/right anchoring regions and primary, middle regions. Inside the anchoring regions, the tensile strength in the bars needs to build up through bonding with concrete. In the middle regions the tensile strength is fully available.

If there are other rebars overlapping in the left or right regions each result point will be individually evaluated. Overlapping left/right regions with different diameters (or spacing) will return the lower as,prov value.

By using hooks, the anchoring region will be reduced to zero. This method offers the possibility to gain a quick, rough overview on provided reinforcement; structural and static details are not taken into account.

Rebar Check with Cutlines#

The diagram based Rebar Check offers another way to compare required and provided reinforcement in slabs.

Note

Cutlines need to be drawn as a model line with line style “SOF_ResultCutLine” in the working plane of the analytical panel. It is recommended to use the command rvt_result_cut_line_small “Result Cut Line”.

Further information about beams

The Rebar Check also supports down- and upstand beams (“T-Beams”). All rebars within the beam width and 10 cm from the edge of the formwork are taken into account. Longitudinal reinforcement outside the 10 cm limit is classified as lateral reinforcement.
