Structural behavior of steel slit damper in steel beam to column connection

ABSTRACTMost of the steel moment resisting frames, damage at the beam-to-column connections during seismic loads. Application of passive dampers in order to prevent damages to the main components of structure has been an interesting subject for many researchers recently. In this present study, perf...
