摘　　要：介绍了根据梁的强度要求和锅炉主框架的稳定要求进行主框架梁截面的选取方法。指出,为了满足锅炉构架稳定性的要求,静力计算的低应力杆甚至零应力杆的存在是完全必要的,仅仅根据静力计算结果确定锅炉构架主框架的截面往往会得出错误的结论。The selection method of the cross section of the main frame beam is described according to the strength requirement of the beam and the stability requirement of the main boiler frame. To fulfill the requirement of the boiler frame stability, the existence of the low stress bar of the static calculation, even the zero stress bar, is completely necessary. The wrong conclusion is usually obtained if the cross section of the main frame of the boiler frame is determined only according to the result of the static calculation.

关 键 词：低应力杆 框架稳定 梁的刚度 梁的强度
