The paper reports on seismic nonlinear analyses of two eight storey reinforced concrete (R/C) buildings designed according to the Eurocodes 2 and 8. Structural seismic performance and safety are evaluated. The nonlinear analyses were performed using a new beam element able to follow the stiffness drop due to cracking and yielding and the ductile cyclic behaviour. It has been validated against experimental results obtained at the European Laboratory for Structural Assessment (ELSA). A first attempt has been made to evaluate the structure safety through their failure probability and results are mainly used for comparison between cases. Results confirmed that EC8 design leads to quite comparable seismic performance of the structures, throughout different design options. Moreover, it has been recognized that seismic performance improves when ductility class passes from lower to higher levels.
