Abstract. This work deals with composite timber-concrete structures. By means of mechanical fasteners dowels or the other connecting systems, timber and concrete can be connected, namely, coupled in new type of girders characterized by better mechanical and load-baring capacity properties. Here, on the base of theory of elasticity and, it is very important, according to rules and recommendations of new-fashioned concepts for design of timber structures and concrete structures, namely, Eurocode 5 and Eurocode 2, based on the limit states of structures, design procedure is briefly given.
The structure of footbridge, at the end of the work, is consists of concrete slab and glued-laminated timber beams, connected by steel reinforced fasteners in the composite structure and here is observed the behaviour of this structure according to ultimate limit states and serviceability limit states.

ANALIZA  SPREGNUTIH KONSTRUKCIJA DRVO-BETON PREMA GRANIČNIM STANJIMA
U radu je data analiza spregnutih konstrukcija tipa drvo-beton. Pomoću mehaničkih spojnih sredstava, moždanika ili nekih drugih sistema za spajanje, drvo i beton mogu biti povezani, odnosno spregnuti u novi tip nosača koji se karakteriše boljim mehaničkim svojstvima. Proračun prema teoriji elastičnosti, posebno prema pravilima i preporukama modernih concepata za proračun drvenih i betonskih konstrukcija datih u Evrokodu 2 i Evrokodu 5 i zasnovanih na graničnim stanjima nosivosti u upotrebljivosti, dat je ukratko.
Ponašanje konstrukcije spregnutog pešačkog mosta, sastavljene od armirano-betonske ploče koja jesa lepljenim lameliranim gredama povezana mehaničkim štapastim spojnim sredstvima analizirano je prema graničnim stanjima.
