摘　　要：结合实例根据《钢骨混凝土结构技术规程:YB9082-2006》[1](以下简称《YB规程》)中计算压弯拉弯工况下钢骨部分分配得到轴力,与截面分析软件XTRACT的计算结果进行对比,结果表明截面在轴拉极限承载力下,《YB规程》计算得到的钢骨轴拉力并不等于钢骨截面的轴心受拉承载力Nc0^ss,而是略小于Nc0^ss。就此讨论了《YB规程》计算结果偏小的原因。According to Technical specification of Steel-Reinforced Concrete Structures:YB 9082-2006(hereafter referred to as YB Code),the axial force was calculated by calculating the part distribution of steel bone under flexure and tension,flexure and compression actions.The results were compared with the results calculated by the section analysis software XTRACT.The results show that the axial tensile force calculated by YB Code is not equal to Nc0ss,of steel section,but slightly less than Nc0ss.The reason why the calculation result of YB Code is too small is discussed.
