Abstract. This paper deals with the composite timber-concrete structures..  By combining timber and concrete in a new type of composite material and using the best properties of both materials (the high tensile strength of timber and the high compressive strength of concrete) a new type of composite structure is obtained, which can have many applications, depending on the different building conditions, due to the certain advantages it has over concrete or steel structures. Here, the design procedures according to the theory of elasticity based on the exact method and approximate method are given in order, and particularly according to the regulations and  recommendations of the modern concept for design of timber structures and concrete structures, given in  Eurocode 5 and  based on the limit states of bearing capacity and usability of structures.

METODE PRORAČUNA SPREGNUTIH KONSTRUKCIJA
OD DRVETA I BETONA T PRESEKA U radu je data analiza spregnutih konstrukcija tipa drvo-beton. Povezivanjem drveta i betona i korišćenjem najboljih svojstava jednog i drugog materijala dobija se novi spregnuti tip konstrukcije za koji se, zavisno od različitih uslova građenja, može naci mnogo razloga za primenu s obzirom na određene prednosti u odnosu na beton i čelik. Ovde su, redom, date proračunske procedure prema teoriji elastičnosti zasnovane na tačnom i približnom metodu i  posebno, prema pravilima i preporukama modernog concepta za proračun drvenih i betonskih konstrukcija datih u Evrokodu 5 i zasnovanih na graničnim stanjima nosivosti u upotrebljivosti.
