英国规范CP110中通常用在设计混凝土梁的应力分布为半抛物线形,它取自CP110图1的应力应变曲线。用方程式计算的结果很复杂,只有采用相应的大量的图表来考虑这些大量的变量才能得到成功的应用。在CP110中关于钢筋混凝土梁有42页图表,每一图表包括很多线条。在图表的另一端给出七个公式,从这些公式中能设计出所有钢筋混凝土梁,还可以把七个公式归并为五个,
The stress distribution in the design of concrete beams commonly used in the British Specification CP110 is a semi-parabolic shape, taken from the stress-strain curve of Figure 1 of CP110. The results of the calculations using the equations are complex and only a large number of charts can be used to consider these large numbers of variables in order to be successfully applied. In the CP110 there are 42 pages of charts for reinforced concrete beams, each of which contains a lot of lines. Seven formulas are given at the other end of the chart. From these formulae, all reinforced concrete beams can be designed. Seven formulas can also be merged into five.
