ABSTRACT
On the other hand, earthquake-induced forces have a dynamic nature and, therefore, only a dynamic analysis (being the most rigorous approach) can meet a realistic assessment [280]. Nevertheless, dynamic analyses are not routinely employed in everyday designs, mostly because of the complex nature of the analysis [281], in particular with respect to inelastic behavior. In addition, different ground motions may bring about different nonlinear responses, so choosing the right excitation is an important, and sometimes determining, consideration [282].
