INTRODUCING ECCENTRICALLY BRACED FRAME SYSTEM EQUIPPED WITH DISTRIBUTOR FUSES WITH STEEL PLATE

Eccentrically braced frame is reckoned as one of the lateral force resisting systems due to its desirable performance in shear as well as ductile behavior of its link beam. In this bracing system, it is intended that the dissipation of energy is achieved by concentrating the formation of plastic hinges in the link beam region. A number of investigations have been carried out by researchers so as to improve the seismic performance and increase in the capacity to form plastic hinges in the link beam zone. According to seismic design code, any type of external elements connected to the link beam or the reduction of the cross-sectional area in this region is not allowed since it will have adverse consequences on the performance of the bracing system. In addition, the observation of the eccentrically braced frame performance in some earthquakes reveals that undesirable buckling of the flange and web as well as the rupture at the edge of the link beam connection to the end stiffener have been occurred.
