To improve the bearing failure behavior of the exterior steel beam-reinforced concrete column joints composed of reinforced concrete columns, joint details using steel column was proposed. Steel column was attached to the lower flanges at right angles to the steel flange. The objective of this study is to clarify the effectiveness of proposed joint details experimentally and theoretically. To clarify the influence of steel column on the bearing failure of the joint, seven T-shaped subassemblages were tested under reversed cyclic loading. All specimens had the same cross sections of the steel beam. The experimental variables were the embedded length of the steel column, whether there is the end plate at the tip of the embedded steel column, and, the arrangement of transverse reinforcement ratio surrounding the steel column. The following remarks can be drawn from the test results. 1) In case of the specimen with a short embedded length of the steel column, the punching shear failure on the upper surface of the steel beam flange was remarkable when the maximum strength was reached. However, in the specimen with long embedded length of steel column, it was not observed the punching shear failure. 2) The maximum strength increased with the embedded length of the steel column. Further, the maximum strength of the specimen with the embedded length of three times of the steel column depths is subjected to bending yield strength of the steel column. 3) It was shown that the transverse reinforcement to surround the steel column and the end plate were necessary to improve the bearing failure of the joint.

This paper presents an experimental study and analysis on three double web plate top and bottom angle steel connections of T-shaped concrete-filled steel column and steel beam under low-cycle repeating horizontal load. The damage form and seismic performance of double web plate top and bottom angle steel connections was studied. The results of analysis indicate that the strength and rigidity of the joint are mainly determined by the strength and rigidity of the thickness of top and bottom angle steel. The thickness of top and bottom angle steel affects the performance of the joint and the joint has good consuming energy capacity and its strength is high. The results provide the theoretical basis to the study and application of double web plate top and bottom angle steel connection joint.

This article researches seismic performance of the joint of cellular steel column and steel beam through simulation of the finite element software. With the change of axial force, we can attain the load-displacement hysteretic curves, skeleton curves under the different axial compression ratio, and then analyze their bearing capacity, ductility, energy dissipation and other mechanical properties. Results show that, the decrease of axial compression ratio is helpful to improve the bearing capacity of specimens. The joints of cellular steel column and steel beam have full hysteretic curve, good ductility and seismic performance.

The article researches seismic performance of joints of cellular steel column and steel beam by finite element simulation. Finite element model is established by using the finite element software reasonably. Considering about the hole position and the distance of center of hole as invariant moments, under low cyclic loading we can attain hysteretic curves and skeleton curves etc. which are compared and analyzed in different opening rate by simulated software. The results show that for a certain axial compression ratio (n=0.45) of joints of cellular steel column and beam, the reasonable opening rate can improve the seismic behavior of the joints.
