Abstract:
The bearing mechanism of a new type joint with core steel tube was studied. The specimens were intercepted from the remnant joints area of being destroyed concrete-filled steel tubular joints specimen. The characteristic of the member of the joint was analyzed by the failure process, the main failure formation and the load and displacement curve in the different load modes. The result shows that the maximal bearing capacity was obtained by loading on the full section of the joint, and the minimal bearing could be obtained by loading on the concrete of the core steel tube. But the minimal bearing is also bigger than the bearing capacity of the CFST column; it meets the joint seismic principle. The core steel tube of the joint has different bearing states under different loading modes. The loading modes of the core steel tube and the looping take restriction effort on the core concrete indirectly.
