V članku z Galerkinovo metodo končnih elementov analiziramo vpliv geometrijske in materialne nelinearnosti na izračunano nosilnost armiranobetonskih ravninskih okvirnih konstrukcij, obteženih s ...kratkotrajno konservativno obtežbo. Pri analizi uporabimo t.i. deformacijske končne elemente. Za te elemente sta značilni velika natančnost in neobčutljivost na vse vrste blokiranj. Obtežno-deformacijsko krivuljo izračunamo z znano Crisfieldovo metodo ločne dolžine. Z računskimi primeri pokažemo: (1) da analiza nosilnosti armiranobetonskih konstrukcij ni odvisna samo od materialne nelinearnosti, kot to pogosto zasledimo v literaturi, temveč v veliki meri tudi od geometrijske nelinearnosti in (2) da pri armiranobetonskih konstrukcijah metoda plastičnih členkov v splošnem ni primerna za analizo nosilnosti
