Abstract

To study the impact resistance of concrete-filled double-tube (CFDT) columns at high temperature, a 3D finite element numerical model of CFDT columns under coupled high temperature and impact was established via ABAQUS finite element software, considering material softening temperature, strain rate of reinforcement effect and the influence of axial force. The results were verified by existing fire tests and lateral impact tests of CFDT columns at room temperature. On this basis, the dynamic response of CFDT columns at different temperatures was analyzed from the aspects of impact force, mid-span displacement, load distribution and damage evolution. Then, the effects of different section forms, axial compression ratio, impact velocity and concrete strength on the impact resistance of CFDT columns were considered. The results showed that CFDT columns mainly exhibit bending failure under coupled high temperature and impact. With the increase of temperature, the impact resistance and flexural capacity of CFDT columns gradually decrease. The fire resistance of CFDT columns is 2.1 times that of normal concrete-filled steel tube columns. The axial force has a negative effect on the impact resistance of CFDT columns. When the axial compression ratio increases from 0 to 0.6, the platform value of impact force decreases by 32.4% at 800℃. The concrete strength has significant influence on the impact resistance of CFDT columns at high temperature. When the concrete strength increases from 40MPa to 60MPa, the platform value of impact force increases by 22.8 % at 800℃.
