If you want to use Teddy Input Language (CADINP) we provide several examples to all kind of topics, also dynamics.
For eigenfrequency you can have a look at the example ase4_eigenfrequencies.dat at Teddy - Data - Examples - ASE - english - ase4…
For earthquake analysis you can have a look at ASE - English - dynamics - earthquake_jb.dat
If you want to use modul DYNA, you can have a look at DYNA - english - storeys - storeys.dat using response spectrum analysis.
If you are not sure, which modul is the way to go, please have a look at our manuals regarding ase and dyna, you can find them at Teddy/SSD - Help - Manuals - All Manuals e.g. ASE p. 2-85 Chap. 2.15
