Abstract:Static loading tests and cyclic loading tests were conducted on different forms of new type of rigid joints in mega concrete filled steel tubular column and steel beam in super high-rise building. The finite element numerical simulation analysis results were compared with the experimental results. The results show that the T-shaped stiffener can effectively transmit the internal force of the steel beam, and can meet the design requirements of "strong column, weak beam and strong joint". It is a reasonable and effective joint construction measures.

Keywords:concrete filled steel tubular column; internal stiffening ring; vertical stiffener; FEM; static test; seismic performance test
