Title: Experimental Research on Concrete-filled Rectangular Tubular Repaired Frame of Low Cyclic Loading
Abstract: A destructive 3-floor 2-span concrete-filled steel square tubular frame model is experimented again.This mode is reinforced on the joint and weakened on the ends of the beam which is called dog-bone weaken to achieve the aim of strong joint,strong anchor,strong column and weak beam.By exerting low reversed cyclic loads on the reinforced model,the seismic performance is analyzed,including the load-deformation curve of the joints,the joint ductility,the joint failure mechanism,the failure characteristics and so on that The results indicate the reinforced concrete-filled steel square tubular frame has a higher carrying capacity and good seismic performance.
