T-Beam
Model to Download
Description
When defining the effective slab widths of T-beams, RFEM provides the predefined widths, which are determined with 1/6 and 1/8 of the member length.
To cover the required transverse reinforcement, RF‑CONCRETE Members and CONCRETE determine the most cost-efficient transverse reinforcement as a reinforcement proposal in accordance with the predefined stirrup diameter.

Background Knowledge for Definition of Effective Slab Width Used for T-beams
When defining the effective slab widths of T-beams, RFEM provides the predefined widths, which are determined with 1/6 and 1/8 of the member length. The background to these two factors is explained in detail.

The deformation is determined for members and surfaces, taking into account the cracked (state II) or non-cracked (state I) reinforced concrete cross-section. When determining the stiffness, the tension stiffening between the cracks, the so-called "tension stiffening," can be considered according to the design standard used.- Can I define a different bar size in the RFEM 6 Concrete Design add-on other than the default bar sizes available in the drop-down?
- Can the RFEM 6 Concrete Design add-on automatically design member and surface reinforcement?
- Why is it not possible to select the user-defined additional reinforcement for the serviceability limit state design in RF‑CONCRETE Surfaces?
- What is the maximum number of reinforcement groups that can be created in a design case in RF‑CONCRETE Surfaces?
- I would like to perform punching design of a floor slab. I have selected nodes for the design, but they are marked as invalid. Where did I make a mistake?
- Is the deformation analysis in state II included in the concrete design in RFEM 6?
- How can I open the interaction diagram from Concrete Design?
- Why are the members not valid for the Concrete Design add-on?
- Where can I activate creep for concrete design?
- Is it possible to design single-layer reinforced surfaces with RFEM 6?
