Question
Is the "extended zone method" used for the fire resistance design in RF‑CONCRETE Columns?Answer
Yes, if you select the National Annex "DIN", the "extended zone method" according to DIN EN 1992‑1‑2, Annex B.2 is used for the fire resistance design.Keywords

Often, models are needed in several projects, like the purlin with columns and knee braces in this example. The dimensions can be changed directly in RFEM or RSTAB by shifting the nodes.
Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- Can I enter a provided basic reinforcement in RF‑CONCRETE Columns?
- When opening an RFEM file, the entries in RF‑CONCRETE Surfaces are lost. Is it possible?
- Is it possible to adjust the initial values of the temperature courses entered for the fire resistance design? For example, I would like to adjust the initial value of the moisture content.
- Is the "extended zone method" used for the fire resistance design in RF‑CONCRETE Columns?
- My model includes several columns with different cross-sections. How can I assign the reinforcement of the column with the maximum loading to the columns with the same cross-section?
- Is it also possible to specify a certain basic reinforcement in RF‑/CONCRETE Columns and use it for the buckling or fire resistance design?
- Why can I specify a "creep-producing permanent load" in RF‑CONCRETE Columns and not in RF‑CONCRETE Members?
- Why do I get the message 28) in RF‑CONCRETE Members, saying that I have to make a "calculation without second order effect" with the internal forces according to the gemetrically linear analysis?
- Why are the values of a column base, head or center on the individual columns only displayed partially for the results from the calculation in RF‑CONCRETE Columns?
-
The design criterion for VEd/VRd,c is displayed as governing, although there should be a shear reinforcement designed. Also, the design of VEd/VRds is missing. Why?
