The deformations of the FE nodes are always the first result of an FE calculation. It is possible to calculate strains, internal forces, and stresses based on these deformations and the stiffness of the elements.
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.
Using an example of a steel fiber-reinforced concrete slab, this article describes how the use of different integration methods and of a different number of integration points affects the calculation result.
![Spans Based on Figure 5.2 from [1]](/en/webimage/039540/3493372/01_Abmessungen_EN.png?mw=512&hash=3cc425f1463bd5981b358d5889e3109e07ae1233)
In order to correctly design a downstand beam or a T-beam in RFEM 6 using the Concrete Design add-on, it is essential to determine the flange widths for the rib members. This article describes the input options for a two-span beam and the calculation of the flange dimensions according to EN 1992-1-1.
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 Table 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 Table 5.5 and Table 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.
In connection with the analytical SLS calculation, I get implausibly large values for the crack width and deformation in the RF‑CONCRETE add-on modules. What is the cause, and how can I fix the problem?
Is it possible to export the results from RF‑CONCRETE Surfaces to Excel? For example, I would need the steel stress of serviceability design.
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.
How can I change the size of reinforcement bars from the American code (#3,#4, and so on) to millimeters in RF‑CONCRETE Members while using ACI?
Is it possible in RF‑CONCRETE Surfaces to model a prefabricated slab or an element slab with different reinforcement layouts; for example, a reinforcement layer in a precast element and another reinforcement layer in the cast-in-place concrete extension?
How can I perform the fatigue design of reinforced concrete and prestressed concrete in RFEM 5? I have found a result combination for fatigue, but cannot find the design in the add-on modules.
