Abstract
A novel energy dissipating device, a butterfly-liked metallic damper (BLMD), is proposed in this paper. The main features of the proposed damper with low fabrication cost are easily assembled and replaced in various damper brace configuration systems, such as toggle brace damper system (TBDS) and diagonal brace damper system (DBDS). A series of experiments for identifying the hysteretic behaviour of BLMDs was conducted. Experimental results showed that a BLMD with a superior hysteretic curve had acceptable ductility and energy dissipation behaviours under quasi-static cyclic loading. In addition, BLMDs were installed in different brace systems in sixteen-story concrete frame structures, and the dynamic responses of the buildings to seismic excitations were compared and analysed. The results indicate that this BLMD provides superior vibration control and can significantly improve seismic performance of structures during strong earthquakes.
