Research on Steel Beam-column Joints of Concrete Filled Steel Tube

摘要

With the increasingly sophisticated theory of concrete filled steel tube (CFST) and its' wide application, how to make the CFST steel beam-column joints (SBCJS) becomes one of the key problems in research. According to the relevant references in and abroad, types and research done on CFST SBCJ are introduced, including outer annular-stiffener type, Inner stiffening ring type connection with anchorages type, beam integral breakthrough type etc. Finally the key problems need to be further studied are promoted.
