Abstract

U ovom radu prikazano je dimenzioniranje nosača izvedenog od armiranog betona uz pomoć metode proračuna čvrstoće. Prije svega dan je kratki uvod u samu povijest betona kao materijala te važnosti proračuna armiranog betona na savijanje. Tematiku savijanja, vrste savijanja, odgovor materijala na savijanje u vidu pojave glavnih naprezanja i trajektorija naprezanja opisani su neposredno prije nego se pristupilo rješavanja primjeru. Nakon obrade teme savijanja pristupilo se rješavanju dva primjera sa cjelokupnim postupkom. Na temelju toga započeta je razrada samog postupka rješavanja popraćenog sa objašnjenjima i obrazloženjima navedenog te se na temelju toga induktivnom metodom došlo do zaključka. Proračun se sastojao od određivanja maksimalnih normalnih i posmičnih naprezanja za pripadajuće presjeke, utvrđivanja veličine, smjera i trajektorija glavnih naprezanja u pojedinoj točki presjeka te grafičke metode upotrebom Mohrove kružnice u svrhu provjere veličine i smjerova glavnih naprezanja dobivenih analitičkim putem. U svrhu što boljeg, jasnijeg i jednostavnijeg shvaćanja samog proračuna, stavke istog su podijeljene po fazama te argumentirane uz potporu primjera iz struke.

Abstract (english)

This thesis describes dimensioning of carrier beam made out of reinforced concrete using a method of calculation of strength. Above all a short introduction was given about history of concrete, significance of calculation of elements made out of reinforced concrete that are effected by bending force.After introduction, force of bending was desrcibed, effects on material and response of material in terms of normal and shear stress were also described in this section. Consequently started explanation of two given tasks with complete procedure. On that premise evoked elaboration of procedure of resolution of given tasks followed up with clarification of procedure itself taken that into consideration with help of inductive method occured conclusion. Computation consisted of determining maximum normal and shear stress for given cross-section, determination of size, direction and trajectory of main stress in specific point of cross-section and Mohr circle as graphical method was used for reviewing the size and direction of stress that was calculated in previous method. For purpose of easier understaning of calculus examples from real life situations were given.
