EXPERIMENTAL BEHAVIOUR OF REINFORCED CONCRETE BEAM TO CONCRETE FILLED STEEL TUBULAR COLUMN JOINTS UNDER FIRE
This paper describes six new tests carded out on reinforced concrete (RC) beam to concrete filled steel tubular (CFST) column joints subjected to the ISO-834 standard fire. The test parameters included the column cross-sectional type, the level of axial load in CFST column, the load level in the RC beam and the beam-column stiffness ratio. Each test specimen consisted of a CFST column and two RC beam segments in cruciform arrangement to represent an interior joint in a building. Four of the composite connection specimens had circular columns and two had square columns. Analysis of the experimental results is carried out to evaluate the influences of different testing parameters on various characteristics of the beam-column connection performance.
