Abstract

Most 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, performance of the metallic yield damper is slit steel damper (SSD) on the steel beam-to-column connection is carried out using Finite Element model. Thus, first this damper and its connection is simulated. After validation of results, the effect of various dimensional parameters including radius slot, of damper on the performance of damper and its connection was investigated. Then various forms of this damper simulated and their effect on the performance of damper and the steel beam-to-column connection is studied. Moment-rotation, Hysteresis curves and plastic strains for each size of radius slot and different shapes extracted from the analysis were compared. Furthermore base shear force for steel frames with and without slit dampers in term of energy absorption and deformation are compared together. Findings indicated seismic behavior fitted to such dampers. The results indicate that the slit damper shows a proper function in absorbing energy. Recommendation for appropriate size and shape of slit steel dampers proposed.
