Abstract (croatian)
U radu je opisan postupak dimenzioniranja armiranobetonskih pravokutnih presjeka prema normi FprEN 1992-1-1 (druga generacija Eurokoda 2). Dimenzioniranje je provedeno na dva načina: tablicama za dimenzioniranje armiranobetonskih pravokutnih presjeka i direktnim analitičkim postupkom. Korišten je proračunski dijagram naprezanje-deformacija betona u obliku parabole i pravca, dok je za čelik za armiranje korišten bilinearni proračunski dijagram naprezanje-deformacija s horizontalnom gornjom granom bez ograničenja deformacije. Zbog toga je kod dimenzioniranja armiranobetonskog presjeka potrebno ograničiti deformaciju u tlačnoj zoni betona. Tablice za dimenzioniranje armiranobetonskih pravokutnih presjeka dobivene su novim postupkom kod kojeg se varira mehanički koeficijent armiranja vlačnom armaturom. Za usporedbu primijenjen je direktni analitički postupak kojim se mogu dimenzionirati armiranobetonski pravokutni presjeci bez upotrebe tablica. Izračunane su limitirajuće vrijednosti koeficijenta visine tlačnog područja za čisto savijanje prema normi FprEN 1992-1-1.
Abstract (english)
This paper describes the design procedure for reinforced concrete rectangular crosssections according to the standard FprEN 1992-1-1 (second generation of Eurocode 2). Design was carried out in two ways: using design tables for reinforced concrete rectangular sections and using a direct analytical procedure. The stress-strain diagram in the form of a parabola-rectangle was used for concrete, while for the reinforcing steel a bilinear stress-strain diagram with a horizontal post-elastic branch without strain limit was applied. For this reason, when designing the reinforced concrete cross-section, it is necessary to limit the strain in the compression zone of the concrete. Tables for the design of reinforced concrete rectangular sections were obtained using new procedure in which the mechanical reinforcement ratio is varied. A direct analytical procedure was used for comparison, which can be used for the design of reinforced concrete rectangular sections without the need to use tables. The limit values of the coefficient of the height of the compression zone for pure bending were calculated according to the standard FprEN 1992-1-1.
