Abstract

V diplomskem delu analiziramo in primerjamo, kako temperaturne vplive definirata standard SIST EN 1991­1­5 in tehnična smernica ZTV­ING 2012. V prvih poglavjih diplomske naloge so na splošno predstavljeni temperaturni vplivi, načini upoštevanja in obravnavan standard ter tehnična smernica. Nadalje je opisan tudi vpliv temperature na prekladne konstrukcije (povzet po SIST EN 1991­1­5), ki služi kot primer bolj natančnega definiranja vpliva temperature na konstrukcijo. V naslednjih poglavjih je prikazan temperaturni vpliv na mostne opornike oziroma ostale delno zasute konstrukcije, najprej z metodo izračuna temperaturnih vplivov po SIST EN 1991­1­5 in nato po ZTVING 2012. Sledi primerjava med obravnavanima metodama. S primerjavo smo ugotovili, da je metoda po SIST EN 1991­1­5, nenatančna, saj ne upošteva vpliva zasutja elementa, vpliva podzemne vode, geometrije konstrukcije in sprememb temperature zaradi menjave letnih časov. Metoda, ki jo predpostavlja ZTV­ING 2012, pa upošteva vse naštete faktorje, zato je bolj primerna za definiranje temperaturnih vplivov. Na koncu je prikazan še računski primer in primerjava rezultatov za obe metodi. Model konstrukcije smo povzeli po resničnem projektu armirano betonske kesonske konstrukcije. Najprej smo definirali potek temperature skozi posamezne elemente kesona pri obeh metodah. Nato smo s pomočjo programa Sofistik izvedli statično analizo in primerjali notranje statične količine ter potrebno količino armature.

Secondary title: Analysis of temperature effects on the deformation stress state of partially inground reinforced concrete structures
Secondary abstract: In this thesis, we analyse and compare how temperature effects are defined by standard SIST EN 1991­ 1­5 and tehnical guideline ZTV­ING 2012. In the first chapters of the thesis, the temperature effects, the methods of consideration, standard and technical guideline under consideration are presented. Furthermore, the influence of temperature on bridge decks is described (summarised from SIST EN 1991­1­5), which serves as an example of a precise and appropriate definition of the influence of temperature on a structure. In the following chapters, the temperature impact on bridge abutments or other partially inground structures is presented, firstly using the method of temperature impact according to SIST EN 1991­1­5 and then according to ZTV­ING 2012. The two methods are then compared. The comparison revealed that the method according to SIST EN 1991­1­5 is imprecise, as it does not take into account the influence of the backfill of the element, the influence of the groundwater, the geometry of the structure and the changes in temperature due to the change of seasons. However, the method assumed by ZTVING 2012 takes into account all these factors and is therefore more suitable for defining temperature effects. Finally, a computational example and a comparison of the results for the two methods are shown. The structural model was taken from a real reinforced concrete caisson structure project. First, the temperature load for the individual elements of the caisson was defined for both methods. Then, using Sofistik, a static analysis was carried out and the internal forces and the required amount of reinforcement were compared.
