Three commonly-used theories including separately semi-steel theory, uniform theory and superposition theory were introduced. Enormous experimental datas were collected to compare among different theories. Four normally construction of concrete-filled rectangular steel tube column steel beam connection were introduced and the innovative through-diaphragm connections were described in detail. Furthermore, the research on special-shaped columns was reviewed and the development on the special-shaped column composed of concrete filled square tubes was summarized.Keywords:composite structure; concrete-filled rectangular steel tube; through-diaphragm connection; special-shaped column
