Each test specimen consisted of a CFST column and two steel beam segments connected by external rings to the CFST column on each side to represent an interior joint in a building. The test parameters included the column cross-sectional type, the level of axial load in the column, the beam-column strength ratio and the fire duration time. The applied load in the column was a constant axial load followed by a cyclical lateral load (applied via the connected beams) with increasing amplitude until failure. It was found that the composite joints after exposure to fire exhibited very high levels of energy dissipation and ductility. The tested results were verified by a nonlinear finite element analysis (FEA) model developed by the authors. Comparisons between the test and finite element simulation results show good agreement, which enable the finite element model to be applied in further research studies of the earthquake-resistant behavior of retrofitted fire damaged concrete-filled steel tubular structures.
