Finite Element Analysis on Behavior of the Joint with Steel Tube Confined Concrete (STCC) Column to Reinforced Concrete Beam
The steel tube confined concrete (STCC) column exhibits excellent mechanical performance. A 3-D finite element model (FEM) using ABAQUS was established to simulate the performance of the composite joints with STCC column and RC beam. Accurate material model, rational element type, and solution method were discussed. Some STCC columns and composite joints with concrete-filled steel tubular (CFST) column and STCC column were modeled based on the model, respectively. The results from FEM are good agreement with the test results. The mechanism of the composite joint was investigated based on the FEM.
