摘要

In this study, a new type of steel block slit dampers (BSD) has been investigated. This type of damper not only provides good seismic performance but can be easily repaired and replaced after a strong earthquake. The stability of these dampers under periodic loading and the hysteresis behavior was also investigated in this study. It should be noted that energy dissipations and plastic deformation are concentrated only in steel slit dampers (SSDs) and plastic behavior of the beam and column, and they are both more energy-absorbing and more economical than SSDs. Therefore, in this study, effort has been made to optimize and increase the energy absorption of these dampers. Therefore, in this study, eight samples with different geometric dimensions have been simulated to develop and increase energy absorption of the steel BSD, and the results indicate that the slit dampers have more ductility and stiffness than those of previous studies, which considerably increased the energy absorption in hysteresis cycles in all specimens.
