Numerical Analysis of Mechanical Behavior of Self-Centering Joint between CFDST Column and RC Beam
The existing connection between the concrete-filled double steel tubular (CFDST) column and the reinforced concrete (RC) beam is difficult to repair and reuse after damage.In this paper, a self-centering joint between the CFDST column and the RC beam is proposed.The self-centering of the joint is realized by prestressed steel strands, and the energ
