摘要
介绍了应用于广州新白云国际机场航站楼连接楼的一种梭形三肢钢管缀板柱 ,对这种新型钢格构柱在轴心压力作用下的极限承载能力进行了足尺试验 .描述了大型受压柱子的加载方法 ,讨论了试验结果 .试验表明这种柱子的破坏模式为结构弯扭失稳 ,其极限承载力达到设计轴心压力的 3.38倍 。
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.
