Concrete Slab with Elastic Support
Model to Download
Due to the FE methodology, it often happens that stress concentrations arise at nodal and line supports. This model shows the possibilities for dealing with such singularity locations.
Model Used in
In RF-PUNCH Pro, you have different options to determine the punching loads on wall corners and wall ends on the basis of the RFEM surface internal forces.
Setting for automatic determination and consideration of the surface load within the critical perimeter
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.
- The calculation of my model results in unrealistically high stresses at many locations. What is the reason?
- How can singularities on membrane surfaces be avoided from form-finding?
- In some areas of the modeled downstand beams or ribs, there are also walls or pilasters. Is it necessary to separate and remove the downstand beams on the walls, or should they continue through them?
- Is it also possible to determine stiffnesses of an existing column instead of a fixed nodal support?
- 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?
- What is the best way to consider steel fiber concrete in the structural analysis software RFEM?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- How can I model a thickened area of my concrete slab in RFEM such as a drop panel?
- Is it possible to design bidirectional ribbed plates, unidirectional ribbed plates, or hollow core slabs in RFEM?
- Is it possible to set user-defined values when viewing solid stress results?
