Abstract: This study presents a design method for the seismic retrofit and rehabilitation of steel moment-resisting frames (MRFs) with composite steel–concrete beams using the minimal-disturbance arm damper (MDAD). The purpose is ...

Abstract: Concrete-filled steel tube (CFT) columns offer significant advantages over columns made of either steel or concrete alone, such as large energy dissipation and increased strength and stiffness. To further improve the seismic ...
