Szukana fraza: [Abstrakt = "The paper presents the analysis of the effect of concrete volume and massiveness of main girders on the wear indicators of prestressing steel based on a conceptual design of a two\-span, beam road overpass with spans of 2×50 m and a width of 20,60 m. This viaduct was designed for the load class A according to PN\-S\-10030\:1985 with an additional vehicle 0.3 × K required by the Investor. The methodology of structure calculations was taken from the PN\-S\-10042\:1991 standard. The conclusions and observations resulting from the simulations carried out, in relation to the obtained indicators of the consumption of concrete and prestressing steel per m2 of the bridge projection and some standard recommendations was presented in this paper."]
