摘要
钢管的局部屈曲使薄壁方钢管混凝土的承载力降低,设置有效的构造措施可以充分发挥其力学性能。基于工程应用和实验研究成果,分析了各种构造措施的工作机理和受力性能,提出了不同情况下的选型和设计建议,供工程设计应用时参考。
Many studies showed that the failure of concrete filled thin-walled square steel tubes(CFTST) was primary affected by local buckling of the tube.The behavior of CFTST can be extremely improved by effective constructional measure.Based on results of engineering application and experimental research,working mechanism and behavior of every constructional measure are analyzed.Selection and design suggestions of various situations are presented.It can be referred to structure design.
