This example was used to show how a member can be provided with an elastic foundation. This includes the influence of the subsoil in the modeling. Member elastic foundations can only be defined for the "Beam" member type.

An elastic foundation can be applied to a member. The foundation is used to include the influence of soil in the modeling. Member elastic foundations can only be defined for the "Beam" member type.
This article draws a parallel between generating an FE mesh for separate objects using the “Independent FE mesh preferred” option, and generating the mesh without using said option.
The evaluation of story drift in a building is crucial to ensure acceptable structural performance by limiting the drift amount. Excessive drift has the potential to induce system instability and may cause damage to nonstructural components such as partitions. This article outlines the procedure for establishing interstory drift according to ASCE 7-22 and the Building Model add-on in RFEM 6.
The fatigue design according to EN 1992-1-1 must be performed for the structural components subjected to large stress ranges and/or many load changes. In this case, the design checks for the concrete and the reinforcement are performed separately. There are two alternative design methods available.
In the Concrete Design add-on for RFEM 6, you can perform the fire design of reinforced concrete slabs and walls according to the simplified table method (EN 1992‑1‑2, Section 5.4.2 and Tables 5.8 and 5.9).
In the Concrete Design add-on, you have the option to define an existing vertically oriented punching shear reinforcement. This is then taken into account in the punching shear design.
Do you have individual column sections and angled wall geometries, and need punching shear design for them?
No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.
In the Concrete Design add-on, you can perform the simplified fire resistance design according to Sections 5.3.2 and 5.6 of EN 1992‑1‑2 for columns and beams.
The following design checks are available for the simplified fire resistance design:
- Columns: Minimum cross-sectional dimensions for rectangular and circular sections according to Table 5.2a as well as Equation 5.7 for calculating time of fire exposure
- Beams: Minimum dimensions and center distances according to Tables 5.5 and 5.6
You can determine the internal forces for the fire resistance design according to two methods.
- 1 Here, the internal forces of the accidental design situation are included directly into the design.
- 2 The internal forces of the design at normal temperature are reduced by the factor Eta,fi (ηfi), then used in the fire resistance design.
Furthermore, it is possible to modify the axis distance according to Eq. 5.5.
Why do I only obtain the total reinforcement in the Results navigator under "Required Reinforcement", and no result for the top and bottom reinforcements separately?
I would like to calculate a prestressed concrete beam. Is this possible in RFEM?
Is it possible to design a prestressed concrete slab in RFEM 6?
Is it possible to use the add-ons for RFEM 6 to design concrete solids?
Which products do you recommend for the structural analysis and design of reinforced concrete structures?
In the table of the objects to be designed in the Concrete Design add-on, punching nodes are listed in the not valid/deactivated column, although I have defined them as punching nodes. How can I fix this?
