    Single-story precast structures with the pinned connections between the columns and the beams have been frequently used in Europe. However, a similar structural solution has been extended to the multi-storey buildings. The aim of this research was to assess the seismic safety of multi-storey precast structures with pinned connections. On the basis of the experiments performed in the framework of the SAFECAST project, a numerical model for both the columns and the connections was calibrated. Using the calibrated models seismic risk was evaluated for the whole set of the regular multi-storey structures which are usually built in practice. The observed differences in the probability of exceeding the limit state as well as the parameters contributing to seismic safety were discussed. In buildings with masses corresponding to the normalized axial force in columns above approximately 0.15, seismic risk increased substantially due to the possibility of the failure of standard pinned connections.
