Abstract

As concrete-filled steel tube (CFST) is widely applied in practical engineering, it is also necessary to study its internal temperature in fire. This paper aims at discovering a simple method for measuring the temperature of CFST’s cross section. Through a series of tests, it is found that Abaqus finite element software can satisfy the request. Studies show that after a 2D modeling method is applied to the temperature of CFST’s cross section under standard fire, the time-temperature curves of relevant points on the cross section are obtained. Under the restrictions of air gap, thermal radiation and the like, the modelled time-temperature curves nearly overlap with experimental curves.
