ABSTRACT
As modern buildings are getting taller, it is necessary to keep pace with this development through innovative methods that carry larger gravity, wind and earthquakes loads. The composite column is one of the systems that has been increasingly used in advanced and high-rise construction. It is a compressionmember that is composed of two ormore different materials which perform jointly as one new stronger element. One type of the composite columns is the concrete-filled steel tube (CFST) columns which will be explored in this paper.
