| Abstract: | Based on the experimental study on the circular fly ash concrete filled steel tubular stub columns, a constitutive relation model of confined fly ash concrete for finite element analysis is proposed by regression analysis and repeated calculations. The validity of the constitutive relation model is verified through the finite element method analysis. The constitutive relation model is suitable not only for the numerical analysis of fly ash concrete filled steel tubes, but also for that of ordinary concrete filled steel tubes. The research is helpful for the numerical simulation of fly ash concrete filled steel tubes. |
| Keywords: | concrete filled steel tube fly ash concrete axial compression constitutive relation finite element method (FEM) |
