Vsebina analize¶
Izvede se nelinearna dinamična analiza po omejitvi pomika omejene ploskve, prikazane na sliki 4.12.1, in nanosu koncentrirane obremenitve na obremenjena vozlišča. Krmilni podatki analize so prikazani spodaj.

Rezultati analize¶
Časovna vrsta pomika nadzornega vozlišča (obremenjeno vozlišče, številka vozlišča 3121), določenega v krmilnih podatkih analize, je prikazana na sliki 4.13.1 in je bila ustvarjena z Microsoft Excel. Spodaj je kot numerični podatek rezultata analize prikazan del izhodne datoteke pomika nadzornega vozlišča (dyna_disp_3121.txt).
