Abstract. The paper reviews the most important analytic expressions, on the basis of the developed industrial countries' contemporary literature, for determination of strength of shear connectors in steel-concrete composite beams. The mechanism of possible failure and basic criteria used for defining of the shear connector strength at composite slabs and composite slabs with profiled sheet. Special analysis has been done in the expressions and recommendations given by Eurocode 4 in the area of shear connector strength, both elastic and rigid. For all the presented regulations, a comparative analysis with our standing standard (JUS) addressing this area is given. Along with the comparative review of the regulations, a commentary on the strength of the shear connectors in composite beams is given.

STATIČKA NOSIVOST MOŽDANIKA U SPREGNUTIM NOSAČIMA
- ANALIZA PROPISA I ISTRAŽIVANJA - U radu je dat pregled najznačajnijih analitičkih izraza, na osnovu savremene literature razvijenih zemalja, za određivanje nosivosti moždanika kod spregnutih nosača čelik-beton. Prikazan je mehanizam mogućeg loma i osnovni kriterijumi na osnovu kojih se definiše nosivost moždanika kod punih ploča i ploča sa profilisanim limom. Posebna analiza izvršena je kod izraza i preporuka koje daje Evrokod 4 u oblasti nosivosti moždanika, elastičnih i krutih. Za sve prikazane propise daje se komparativna analiza sa našim (JUS) važećim standardom koji tretira ovu oblast. Uz uporedni pregled pravilnika dat je komentar o nosivosti moždanika u spregnutim nosačima.
