  • To investigate the mechanical properties of RC columns confined with self-compacting and micro-expanding concrete filled circular steel tube (SMCFCST) under axial compression, 8 confined RC columns and 1 unconfined RC column were designed and fabricated, and an axial compressive test was conducted. The test parameters including the thickness of the steel tube, the strength of self-compacting and micro-expanding filling concrete, the type of the filling concrete and the magnitude of the initial axial pressure were considered. The failure modes of specimens and the loading data were recorded, while the load versus vertical deformation curves and the load-strain curves were depicted accordingly. The results showed that the peak loads and ductility of the RC columns were significantly improved after being confined by SMCFCST. The peak loads of the confined columns were apparently increased with the increase of the thickness of steel tube. The peak loads of the confined columns were slightly increased with the increase of the strength of self-compacting and micro-expanding filling concrete. However, the effects of the type of filling concrete and the magnitude of the initial axial pressure on the peak loads of the confined columns were negligible. The formula from Technical Code for Concrete Filled Steel Tubular Structures (GB 50936-2014) was modified to obtain the predictive formula of the bearing capacity of the SMCFCST confined columns under axial compression. The average value of the ratio of the predicted value to the test value was 0.956, and the standard deviation was 0.064.
