摘要：
Monte Carlo Simulation is implemented to analyze the reliability of the ordinary concrete-filled steel tubular (CFST) and tie bar CFST short columns under axial compression. The influences of different section shape, material types, load combination, load ratio, stirrup ratio and stirrup strength on the reliability indexes are evaluated. The results show: Properly configuring tie bars in ordinary CFST can greatly improve the reliability index of CFST by 20-40%; When using the same material and the same load combination, the reliability index of the circular section is the lowest; for CFST axial compression members with the same section shape, when the ratio of office live load to dead load is equal to 1.0, the higher the steel strength and concrete strength, the greater the reliability index.
