| Abstract: | A 3-floor 2-span concrete-filled steel square tubular frame model was designed. Inner diaphragm joints were used in the frame model. The quasi-static experiments were carried out. By exerting low reversed cyclic loads on the concrete-filled steel square tubular frame, the seismic performance was analyzed, including the load-deformation curve of the inner diaphragm joints in the concrete-filled steel square tubular frame, the joints' ductility, the joints' failure mechanism, the failure characteristics, and so on. The results indicate that the inner diaphragm joints in the concrete-filled steel square tubular frame have good seismic performance. |
