Abstract

Završni rad bavi se temom savijanja nosača izrađenih od različitih materijala. U prvom dijelu rada, navode se vrste savijanja i izvode izrazi vezani za pojedinu vrstu savijanja, te se opisuju teorijske postavke. Nadalje, rad obrađuje pojam savijanja kompozitnog nosača kroz teorijske izvode i numeričke primjere. Detaljnije se bavi izračunom naprezanja u kompozitnom elementu, primjenom teorije elastičnosti, kroz dvije osnovne metode. Proračun se odvija na primjeru armiranobetonske grede, koja je jedan od najkorištenijih kompozitnih materijala općenito. Na kraju, uspoređuju se rezultati, te opisuju razlozi podudaranja i odudaranja pojedinih rezultata. U radu se koriste i kombiniraju, zakonitosti iz znanosti o otpornosti materijala i zakonitosti iz dimenzioniranja armiranobetonskih sklopova.

Abstract (english)

The final work deals with the terms of reference of bending of girders composed of different materials. The first section of the work contains types of bending, derivative expressions related to the particular type of bending, and describes the theoretical assumptions. Furthermore, the work describes the occurrence of bending of a composite beam through theoretical expressions and numerical examples. Detailed, the work calculates the stress in the composite element with the application of the theory of elasticity through two basic methods. The calculation is based on the example of reinforced concrete beam, which is one of the most used composite materials in general. Finally, the calculations are compared in order to describe the reasons behind the matching and unmatching of the individual results. The principles of mechanics of materials and the regularities of calculating reinforced concrete are used and combined in the final work.
