For the Ansys, I suggest you to visit the respective University of Alberta Ansys Tutorial for Harmonic Analysis (see http://www.mece.ualberta.ca/tutorials/ansys/IT/Harmonic/Harmonic.html).
Essentially,after getting your beam mesh with displacement boundary conditions, you need to add the force amplitude (like in static). Next, go to the type of analysis and choose Harmonic, define the frequency range (e.g. 1 to 400) and number of frequency steps (keep it
hi thank's in real i now how make this, but in interpretation of the resulte i need how to obtain the hysteric curve in the beam with semi-rigid connection.
i now how to build the model but the resulte of the curve of hystiric loops of (Moment -rotation) i don't now it
Hi you need to divide your load and apply like load step file, you can apply like displacement or load (same result) such as in this code below i divid displacement 5 load step
