To set minimum ratings factors in Eriksson Culvert, open the Load and Resistance Factors dialog box, and in the lower right-hand corner, set the Load Factor Multipliers to whatever you want the minimum ratings factors to be. For example, when you first start the program, these factors should be set to 1.0.
In the Text Report (this example is in Design Mode), you can see that the lowest (or controlling) ratings factors are just above 1.
Now open the Load and Resistance Factors dialog box and set these factors to 1.2. This should ensure a minimum ratings factor of 1.2.
Going to the text report, we can now see that the lowest (or controlling) ratings factors are just above 1.2.
