Hi all,
I want to observe how the modal frequencies varies with time ( in a model built with time dependent properties) and each stage. Say for example after 1 year, 5 years, 10 years etc. I used the non linear staged construction analysis for this purpose. But I could only observe the deformed shapes at end of each stage construction.
I would be very much grateful if you can guide me how to obtain the modal frequencies (and associated mode shapes ) for at least first three modes using non linear staged construction analysis in SAP2000.
Thank You in advance for your time and consideration in this regard
