Design of a Shear Joint
RF-CONCRETE Members also includes the design of a shear joint. In order to perform this design, you should select the "Shear joint available" check box in window 1.6, Shear Joint tab.
In this tab, you can also define the location, roughness, possible reduction of joint width, and possible stress perpendicular to the joint surface. The settings apply to the respective members selected in the reinforcement group. If it is necessary to define different properties of shear joint members to be designed, you can create several reinforcement groups in window 1.6.
In addition to entering shear joint properties, the new "Details" dialog box provides a global check of the analysis method for shear stress in shear joints. On the one hand, there is the equation from Eurocode 2, Clause 6.2.5; on the other hand, there is a general method that determines the shear stress using the difference of longitudinal force in the added concrete part from the general integration of stresses.

This article deals with rectilinear elements of which the cross-section is subjected to axial compressive force. The purpose of this article is to show how very many parameters defined in the Eurocodes for concrete column calculation are considered in the RFEM structural analysis software.
- In RF‑CONCRETE Surfaces, I obtain a high amount of reinforcement in relation to a lever arm that is almost zero. How is such a small lever arm of internal forces created?
- When converting from the manual definition of reinforcement areas to the automatic arrangement of reinforcement according to Window 1.4, the result of the deformation calculation differs, although the basic reinforcement has not been modified. What is the reason for this change?
- Why do I get a discontinuous area in the distribution of internal forces? In the area of the supported line, the shear force VEd shows a jump, which does not seems to be plausible.
- Is it possible to perform design without an additional reinforcement in RF‑CONCRETE Surfaces?
- I obtain different results when comparing the deformation analysis in the RF‑CONCRETE add-on modules and another calculation program. What could be the reason for this?
- For the design, I can only select the surrounding reinforcement for a rectangular cross-section. Why?
- What does the "Crack formation in the first 28 days" option means?
- I have recently purchased RSTAB with the CONCRETE add-on module. Can I use it to perform the stability analysis of reinforced concrete columns?
- Why do RF‑CONCRETE Members or CONCRETE determine a significantly higher provided reinforcement than the required reinforcement?
- Why do I get Error No. 10203 for a result beam when performing design with RF‑CONCRETE Members?
