Abstract

Završni rad obrađuje tematiku proračuna konstrukcija po teoriji plastičnosti. U radu su
opisane glavne postavke proračuna prema graničnim stanjima u odnosu na teoriju elastičnosti.
Na primjeru ravnog štapa opterećenog na savijanje objašnjen je način otkazivanja nosivosti
presjeka. Opisani su uvjeti plastičnosti te metode proračuna statički neodređenih konstrukcija.
Riješena su dva numerička primjera na tipskim statički neodređenim konstrukcijama:
kontinuiranom nosača preko više raspona te okviru. Na kraju rada su opisana svojstva
plastičnih materijala te je na primjeru čelika objašnjena važnost plastičnosti pri obradi
materijala.

Abstract (english)

The thesis deals with the structural design according to the theory of plasticity. The work
describes the main settings of calculations according to limit states in relation to the theory of
elasticity. The example of a straight rod loaded in bending is used to explain the method of
cross-sectional failure. The conditions of plasticity and the calculation methods for statically
indeterminate structures are described. Two numerical examples were solved on typical
statically indeterminate structures: a continuous beam over several spans and a frame. At the
end of the paper, the properties of plastic materials are described and the importance of
plasticity in material processing is explained using steel as an example.
