Structural Performance of Partially Confined Concrete-Filled Steel Circular Tubular Columns Under Cyclic Lateral Loading
This paper presents an experimental investigation on partially confined concrete-filled circular steel tubular (PCCFST) columns to explore the use of circular hollow section (CHS) configuration as partial inner confinement to the concrete-filled steel tubular (CFST) column. A total of four columns, three PCCFST and one CFST were tested under combined axial and cyclic lateral loadings. In this study, hysteretic behavior, flexural strength, ductility coefficient, energy dissipation capacity and failure mode of the PCCFST columns were investigated as a function of the height of inner CHS tube. Based on the experimental results, it was seen that the height of the inner CHS has evident influence on the energy dissipation capacity of the column. It has been found that, till 0.5D height of inner steel tube, there is no change in the hysteretic curve. For 1.5D height of inner steel tube, the flexural strength, ductility coefficient and energy dissipation capacity of CFST column were enhanced by 12.2%, 14% and 20.5%, respectively. This shows the structural viability of PCCFST column in the region particularly prone to seismic activity.
