Redistribution

In MasterKey Concrete moment re-distribution of beam support moments may be carried out post-analysis.

You can either do interactive re-distribution from the beam reinforcing editing area, or set the redistribution values from the re-distribution screen. 

Interactive re-distribution has the advantage of allowing you to tailor your redistribution.

In the example adjacent we were able to reduce the top right steel to reduce material. If we had re-distributed by more than 15% on the right then we would have needed more mid-span bottom steel.

The distributed moment is drawn with a faded grey line in the BM diagram.

Once you have decided on the degree of re-distribution for the key elements then switch to the main re-distribution screen using the control Redistribution tab.

Here you choose a value of re-distribution and then pick the ends of the members you wish to re-distribute. Repeating for all the different percentages you wish to re-distribute by.
