Question
What is the critical load factor and how is it possible to determine it?
Stability Analysis - Torsion Available
I get the message "Existing torsion -> no stability design possible". Why does this appear and what can I do?
Question
In compliance with DIN 1054, the allowable contact stress "Sigma_all" has been entered for the soil contact stress analysis. RF‑FOUNDATION Pro requires a "characteristic value" to be entered. How are both approaches of DIN 1054 and EN 1997‑1 compatible?
Question
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?
Question
Is it possible to design a model with a pile foundation in RFEM?
Question
I am designing a tapered beam and I get the message "Non-designable: ER051 Moment about z-axis on asymmetric cross-section, taper, or set of members". Why?
Question
What is the meaning of the warning message ER061) Minimum amplifier of design loads <1?
Question
Why is the cracking moment Mcr smaller for biaxial bending than for uniaxial bending?
Question
In RF‑CONCRETE Surfaces, I get non-designable situations at some locations. Note 5 is displayed: "Allowable compressive stress of concrete in strut direction exceeded."
Design of Asymmetric Cross-Section
I design an asymmetric cross-section and get the message: "Non-designable: ER051) Moment about z‑axis on asymmetric cross-section, taper or set of members." Why?
Question
Why do I get such a small amount of reinforcement for the upstand beam? The amount of reinforcement for the downstand beams is significantly larger.
Question
Which formula is used for the calculation of the elastic torsional buckling force for torsional buckling Ncr,T in RF‑/STEEL EC3?
Bending Design of Block Foundations
How is the static depth d calculated in the bending design of block foundations (calculation as equivalent beams)?
Question
How can I calculate a timber-concrete composite floor with cross-laminated timber?
Question
Is the plastic section modulus of cross-sections implemented in your program?
Question
Is it possible to design bidirectional ribbed plates, unidirectional ribbed plates, or hollow core slabs in RFEM?
Question
How can I change the colors of the graphical display of a reinforcement?
Calculation of Cable
When calculating a cable using the STEEL EC3 add‑on module, there is the error message "Incorrect characteristic stresses for material No. 1! Please correct this in Table 1.2."
Question
I would like to perform a stability analysis of the upper flange in a long truss. What is the best way to proceed?
Question
Why is it not possible to select "ULS", "SLS", or "ULS/SLS" for the "required reinforcement"? I can no longer find the selection for this.
Question
I would like to connect a column rigidly to a girder flange. However, in the RF‑/JOINTS Steel - Rigid add-on module, beams are always connected to a column flange. How can I create a continuous beam?
Question
We want to reinforce a floor slab of a round vessel radially or tangentially.Is there a way to calculate not an orthogonal reinforcement, but a radial or tangential reinforcement?
Question
How can I perform a stability/buckling analysis on a plate structure?
