The above expression is a function of 3 parameters and again can be simplified with the assumptions explained above, into:

100000 113,65

This curve is represented in the following figure and given in numerical form in table 7.3. It can be seen that good agreement is obtained between theory and prEN table. The small differences observed are due to the need to use commercial bar diameters in table 7.3.
