Experimental Research on Seismic Behavior of New Joint between Concrete-Filled Square Steel Tubular Column and Steel Beam

Abstract:

A new type of joint between Concrete-filled Square Steel Tube columns and steel beam is proposed in this paper, and the seismic behavior of this type of joint under low-reversed cyclic loading experiment is researched. Ductility behavior, dissipation of seismic energy of this joint under horizontal, repeat load are analyzed. The experimental results showed that all specimens have good ductility and energy dissipation capacity. The story angle drift ductility ratios are μ=3.23~3.63, and the equivalent viscous damping coefficients are he=0.25~0.35,which meet the needs of the code for seismic design of building.
