The main goal of the thesis is to present and use the novelties that are introduced by the draft of new Eurocode 8 in the field of earthquake-resistant design of precast reinforced concrete buildings. Some novelties in the design of precast reinforced concrete buildings in comparison to the current version of the code are presented. We describe the definition of the acceleration spectra, requirements for the shear reinforcement in columns and improved instructions on how to design a dowel connection between a column and a beam. The use of the draft of the new Eurocode 8 is then demonstrated by designing variants of a single storey reinforced concrete building. The building is designed for ductility class medium according to the current standard (SIST EN 1998-1). In addition, it is designed according to the working draft of the new standard, where the newly introduced ductility class DC3 is taken into account. The design is limited to columns and beam-to-column connections, which proved to be the critical structural components in past earthquakes. A comparison between the results of the design is presented. The designed structures are compared in terms of strength and deformation capacity. The deformation capacity was calculated by utilizing the model introduced by the draft of the new Eurocode 8. It turns out that the strength of columns increases, but the deformation capacity is practically not affected by the design rules introduced in the draft of the new standard.
