The UMomPF function performs ultimate load analysis for codes using the partial factor approach, including Eurocode 2. The input for Eurocode 2 includes an optional table allowing alternative values to be input for various parameters, including stress reduction factors, and stress block definition values. It was recently pointed out that some of these parameters were having no effect on the results. This has now been fixed, and the revised file has been uploaded to:

The example below shows results for a section with axial load close to the balance load, first with default Eurocode 2 parameters (click on any image for full-size view):

Then with the reduction factors adjusted to be equivalent to the AS 3600 value for sections in compression, and the stress block set to rectangular, with stress and depth equal to the AS 3600 values for 50 MPa concrete:
