RF-IMP/RSIMP Add-on Moduls | Generation of Equivalent Geometric Imperfections and Pre-deformed Initial Structures
Depending on stiffness, mass, and damping, structures react differently to wind action.
A member was divided by several nodes. When I apply the imperfections, each partial member gets its own imperfection.
How can I define an imperfection across all partial members?
- I have generated a pre-deformed equivalent model using RF‑IMP by means of a pre-deformed FE mesh. Is the equivalent model considered for all load combinations nov, or do I have to make further settings?
- How do I manually enter a precamber to a member as an imperfection?
- Is it possible to display the mean value of the line support results?
Is it possible to specify shrinkage effects as loads?
- Why is no support force displayed even though I have bedded the member?
Is it possible to change the font size of dimensions?
- I would like to apply only to a part of the surface a rectangular load. How to do it?
Which units are specified in the result display of the support reactions (kN or kN/m)? A note about this is missing in the graphic.
In the case that the support reactions are given in kN/m, for which distance does the value apply?
- I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
