Abstract
The work summarized in this thesis is devoted to investigate the seismic
response of eccentric braced frames in simple and dual configuration
(namely structural systems made of moment-resisting frames in parallel
with braced frames) designed with the combined use of high strength
steel (HSS) and of mild carbon steel (MCS). In particular, the first part of
the thesis concerns the issues related to both design and verification
check. In the second part, a wide and comprehensive parametric study is
described and discussed in order to characterize the performance of an
ensemble of reference buildings. To this aim, several design parameters
are examined, such as: the number of storeys the length of bays, the
grade of steel, the steel column sections and the soil foundation. The
results from both nonlinear static and incremental dynamic analyses are
presented and discussed thus allowing to draft novel design to improve
the seismic performance of the examined structural typology. In the
third part of the thesis, on the basis of the numerical results obtained
from the parametric study, a preparatory study addressed to design the
experimental setup for a real scale steel building made of dual Eccentric
braced frame having removable links. The aim is to investigate the
recentering capacity that the moment resisting spans may provide.
