Paper Title:
One-Dimensional Dynamic Performance of Concrete-Filled Steel Tube
  Abstract

The paper puts forward the one-dimensional strain rate related dynamic constitutive model of concrete-filled steel tube. The calculation results are in good agreement with the experimental results. Uniaxial compression performance finite element analysis at the strain rate among 10/s-5—10/s-2 is completed based on the conclusions. The results showed that considering concrete strain rate effect, the bearing performance of CFST is obviously changed. It showed that with the strength of concrete and strain rate increasing, ultimate bearing capacity of concrete-filled steel tube is improved and ductility is reduced. With the confining ratio and strain rate increasing, the ultimate bearing capacity and ductility of CFST are improved. With the slenderness ratios and strain rate increasing, the ultimate bearing capacity and ductility are reduced.
