摘　　要：分析了轴向力对压弯构件弯曲变形的影响,导出了压弯构件的附加弯矩和最大弯矩的一般表达式.通过实例计算,定量分析了附加弯矩对压弯构件的最大弯矩的影响,得出了在对压弯构件最大正应力计算的实际问题中,可否忽略附加弯矩的判别条件.The article analyses the influence force of axes for combined deformation.The formulate of (maximum) bending moment taking into account this influence is induced.Overpass calculate examples and (analysis,)the distinguishing condition is introduced that additional bending moment is neglected to calculate the (maximum) normal stress of combined deformation practically.

关 键 词：压弯构件 附加弯矩 最大弯矩 最大正应力
