Modelling of Member Perpendicular to Existing Member
For a frame trussed from below, compression members are to be modelled perpendicular to the inclined beam. The member length and the intersection with the horizontal beam are defined.
One way to do this would be to rotate the grid by 90 degrees and place the origin in the respective node. Then you can place the compression members along the grid points.
Another possibility is the modeling with a polar coordinate systems. However, this requires precise angle information.
So the solution with the least modeling effort is to use the alternative input modes of members. You can see in the picture that only the member length is required in that case. If you point on the members with the mouse then the member preview appears.

In RF-/FOUNDATION Pro, the foundation design requires the definition the corresponding loading (load cases, load combinations, or result combinations) for the different design situations (STR, GEO, UPL or EQU).
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.
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- I would like to convert the load from a surface load to a line load, that is, to apply it to the individual beams. How can I do this without using an auxiliary area?
- Is it possible to transfer properties, such as the cross-section, or the surface thickness as well as the material of a surface, of an existing element to a new element?
- How can I get the member end forces to design the connections?
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- A rigid member should only be able to absorb tensile forces or only compressive forces. What are the options for considering these nonlinearities in the calculation?
- How do I display the nodal displacements graphically?
- Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
- Can I quickly optimize all cross-sections in my model by using internal forces?
- Why do I obtain great differences in results for both the deformation and the bending moments when applying inclination by using imperfection to a single member and an articulated set of members with the same total length?
