Thank you for your reply System Theory, I think you have a point about the spring configuration causing disturbances in the frequency domain (I hope this was your point...). I've plans to improve the physical model by installing a joint where the springs are attached. I'm hoping that this...

The system is a sectional bridge deck model, similar to the one found here (figure 3): http://www.ias.ac.in/jarch/sadhana/3/00000182.pdf" I want to create a model based on measured data but with parameters that have physical meaning. I've done vertical and torsional step responses. From...

Hi everyone, I'm dealing with system identification for the first time in my life and am in desperate need of help :) The system is spring-mounted and I'm analyzing the vertical and torsional displacements. However, it seems like the vertical and torsional oscillations are coupled (shouldn't...

I have a theoretical question. Does a structure's natural frequency have anything to do with the highest frequency of which it can vibrate? Or can the structure vibrate in any multiple of the natural frequency (until it brakes...)?
