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.
