Eigenvalue of analysis for series of sections of bridge deck

I want to do eigenvalue analysis for whole bridge deck. Can someone help please ?

Hello Anisha,
you will find a few examples that might help you, if you open file>examples>dyna or have a look at the user Manual “Dynamic Analysis”, section 3.10 “EIGE-Eigenvalues and Eigenvectors”.
