Abstract

In order to research the interface bonding property of concrete-filled steel tube(CFST) with the corrosion time,simulation test of CFST was done in corrosion environment,in which application of 3.5%NaCl solution to the inner surface of steel pipe.It was completed the push-out tests on 10 round CFST specimens with the corrosion time as basic parameters.The test results indicated that concrete-filled steel tube bond strength was increased in the initial stage of corrosion,with the corrosion time extension,the interface bonding strength appeared to decline and tended to be steady.Based on the test results,the load-slip curves of each specimen were obtained.It was analysed the corrosion influence on the CFST interface bonding property,and researched internal links of corrosion time with interface bonding strength through the carbon steel in NaCl corrosion mechanism.
