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.
