摘要
矩形变截面梁的截面高度和弯矩值沿梁长是变化的．本文考虑了荷载的大小，截面宽度、材料强度等有关因素，引进新的目标函数，利用松弛变量法，推导出所需要的最大纵向配筋断面面积计算的简洁公式．
The heights and bending moments of rectangle changing section beam is changed with its length. In this paper, the author considered loading conditions, Section width and material stength,quoted a new objective function and derived the formula to calculate maximum section area of steel. The formula is convenient for calculating engineering structures.
