Abstract

Abstract

A total of 3 concrete filled steel tubular short columns and 6 polypropylene(PP) fiber mortar filled steel tubular short columns were tested under axial compression dynamic load.The influence of the strain rate and diameter thickness ratio on the dynamic performance of the PP fiber mortar filled steel tubular short columns was investigated.The test results showed that the ultimate bearing capacity and the initial elastic modulus were increased by 5.80% and 42.8% respectively, while the strain of peak load was decreased by 6.77% when the two millimetres of PP fiber mortar filled steel tubular short column with the strain rate of =10-4 s-1 was compared with the strain rate of =10-5 s-1.In the scope of test parameters, strain rate was more effective to PP fiber mortar filled steel tubular short column than concrete filled steel tubular short column in the scope of ultimate bearing capacity and the peak load strain, while the result was opposed in the elastic modulus.
- strain rate,
- elastic modulus,
- PP fiber mortar filled steel tubular short column,
