Abstract

Abstract

Two 1∶2 scaled single-span pin-connected steel frame structures with two floors were designed and fabricated. One is pin-connected steel frame with common braces (FMB) as the comparison frame, and the other is pin-connected steel frame with self-centering energy dissipation braces (FMD). The experimental study and comparative analysis of the two frames under quasi-static loading were carried out. The results showed that the out-of-plane instability and buckling occured in FMB during the loading process, local warpage also occurred in the beam-brace connection zone. The FMB was almost no energy dissipation capacity or self-centering capability. Self-centering energy dissipation devices in FMD played the energy dissipation and self-centering function, and other components kept in the elastic. After loading, no damage occurred to the structure. The structure possessed good energy dissipation capability and could restored to its initial station after loading. Compared to FMB, FMD owned about the same yielding load, higher sidesway resistance, greater ductility, stronger energy dissipation and self-centering capacity.
