U ovom diplomskom radu napravljeno je modelsko ispitivanje armiranobetonskih i čeličnih greda. Ispitivani su prototip i dva modela u mjerilu 1:2 i 1:3. Napravljen je proračun prototipa, te sukladno zakonima modelske analize napravljen je proračun modela. Proveden je numerički proračun prototipa i modela te su dobiveni rezultati uspoređeni sa eksperimentalnim rezultatima. Izrađeni modeli i prototipi su ispitani u laboratoriju. Pomaci su eksperimentalno mjereni na polovici i trećini raspona. Usporedba rezultata je napravljena na polovici raspona.

In this thesis, model testing of reinforced concrete and steel beams was performed. Prototype and two models were tested in scales 1:2 and 1:3. Calculation of prototype was done and according to the rules of model analysis, calculation of models was done. Numerical calculations of prototype and models were compared to experimental results. Models and prototypes were test in a laboratory. Displacements were measured in the middle and one third of span. Comparison of results was done in the middle of span.
