    Abstract:

    The fire resistance performance of concrete component is very important for building structure safety. A test method was proposed for concrete column at high temperature under compressive loading. Firstly, a concrete column was placed under constant compressive loading, and then, the performance of the concrete column was tested at different constant temperatures after heating. The performance of the concrete column at high temperature was evaluated by first spalling temperature, spalling degree, fracture shape and axial compressive strength in the course of heating. Test results of three groups of concrete prisms show that this method can reflect the performance of concrete column at high temperature under compressive loading, and also has the advantages of low requirements for test instruments, convenient testing methods and reliable results.
