Cyclic behaviour of prefabricated connections for steel beam to concrete filled steel tube column

Mechanical properties of CFT column and steel beam joint with inner stiffening ring was analyzed by using FEA program ANSYS. Simultaneity, using correlative theory of circular beam, stress distributing rule of stiffening ring was induced. The multi-dimensions joint is different from the annular plane in bidirectional. Not only the turn of beam-annular stress concentration, but also lied on the oblique angle, smaller of the angle easier to form the biggest stress area. Thickness of stiffening ring can impact on load absorption of enforced plane. Results of FEA are valuable methods for design of stiffening ring.

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.
