What difference exists between the two rod types "rib" and "eccentric beam rod"?


The rod type "rib" is primarily suitable for reinforced concrete elements, since the participation of the plate in the design is usually taken into account here. When defining the "rib" type of bar, the integration of the internal forces as a result of plate participation is carried out internally in the program.

If you decide on the type of rod "rib", note the activation / deactivation of the effective participation of the surface, see Project Navigator "Show", "Results".

If internal forces are required exclusively for the rod without taking into account the plate interaction, the rod type "eccentric bar" must be selected.

In the design with the aid of an additional module, the same results apply to the "rib" rod type as to an eccentric beam rod.
