“…In the literature, there are several works studying dynamic effects in steel structures. In general, such research can be divided into the study of building vibrations globally (Housner & Brady, 1963;Satake & Yokota, 1996;Kohler;Davis, & Safak, 2005;Kazantzi & Vamvatsikos, 2020) and in the study of its parts, such as floors and connections (Chan, 1994;Chan & Ho, 1994;Chui & Chan, 1997;Tremblay, 2005;Culau, Quintas, & Gomes, 2018;Ribeiro, Gomes, Ferreira, & Calenzani, 2018). In particular, regarding this work, semi-rigid connections are widely studied, but there are few studies on the effect of semi-rigidity on structural behavior and especially on vibrations.…”
