| Abstract: | This paper describes a battened tubular column with three chords like two triangular pyramids put together base to base,which is used in New Baiyun International Airport Passenger Terminal,Guangzhou,China.A full-scale test is carried out on ultimate bearing capacity of the new type of built-up steel column under axial compression.A method of loading the large size of column is presented and experimental results are discussed.The test indicates that the failure mode of the column belongs to structural flexural-torsional instability,and its ultimate bearing load comes to 3.38 times its design axial compression that meets the specification for design of the column. |
