摘　　要：介绍了国内3个设计规程对偏心受压钢管混凝土构件的设计公式以及理论依据,借助已有的试验参数,采用3个规程分别计算了不同偏心距和长细比下的偏心受压构件承载力,并且与试验结果进行对比。结果表明,对于极限承载力,《钢-混凝土组合结构设计规程》(DL/T 5085-1999)相对偏于安全;但从规范计算值和试验结果的比较结果看,《钢管混凝土结构设计与施工规程》(CECS 28∶90)的计算值与试验值吻合相对较好。The three codes design formulas and their theoretical basis of concrete-filled steel tubular columns under eccentric load are presented. Fifty-one concrete-filled steel tubular columns are cited as examples from reference one. When the eccentricity and slenderness ratio are changed, respectively, according to the parameters of tests cited, using the three codes design formulas, ultimate carrying capacity of columns are calculated and compared with the test results. For the ultimate carrying capacity, ＂Code for Design of Steel-Concrete Composite Structure＂ （DL/T 5085 - 1999） is relatively conservative, but for the degree of agreerment of codes with tests, ＂Code for Design and Construction of Concrete-Filled Steel Tube Structures＂ （CECS 28 ： 90） is relatively better.
