Applying a dynamic load

Hello,

I would like to ask how to implement a dynamic load on a node in SOFiSTiK. I recently started working with SOFiSTiK for a university project, so my experience is still limited.

My goal is to reproduce a shaker excitation on a bridge: a sinusoidal (harmonic) force applied at midspan. I want to use this excitation to compute the bridge response (in particular nodal accelerations) and compare the results with acceleration measurements from field tests.

Could you please explain a workflow to define and apply such load?

Thank you very much in advance

You have several examples that you can adapt to your need, like this:
