摘要

Experience and research developments have led to significant advances in the subject of seismic engineering over the past 40 years. In the particular field of seismic design, the development of a newgeneration of design codes such as the Eurocode 8 is an important milestone. Although this code still promotes the use of classical seismic design approaches deeply imbedded in current practice, e.g. force-based approaches considering the use of behaviour factors (q-factors) and enforcing capacity design principles, Eurocode 8 also encourages the use of more advanced methods of analysis. Although the core of such analysis methods, i.e. nonlinear static and nonlinear dynamic analysismethods, can be seen to be reasonablywell established, there are other issues of the design process which must be addressed. Namely, an adequate safety format, similar in scope to the one involving linear analysis methods, is yet to be explicitly addressed in a framework which foresees the use of nonlinear analysis methods.
