000009715 520__ $$2eng$$aAn experimental investigation into the seismic properties of the typical joints used in the 610m high Guang-zhou New TV tower has been conducted. All specimens consist of a concrete-filled CHS column (circular), a steel bracket, two steel circular hollow section (CHS) beams and two steel CHS bracings. Whereas the members are not coplanar, which result in that the bracket is subjected to combined torque and small moment. The stiffened bracket is used to connect the column and the beams that are directly welded to the bracket. The present paper mainly presents the experimental and finite element analysis (FEA) results of the bracket to beam connection. Stiffened connections with various dimensions are compared with the unstiffened ones to find out the effect of stiffeners on the seismic properties of the connections. It is found that both the ultimate strength and the stiffness of the joints have been improved compared with the unstiffened joints. Meanwhile, a theoretical model indicates that the small moment has little effect on the seismic properties of the connections.
