Inter Cross Section Slope Limit Trimming
Once cross sections have been individually trimmed, they are trimmed relative to each other. This Inter Cross Section Slope Limit trimming effectively trims the top and bottom elevations of adjacent cross section to limit the slopes between them.
This is done because compression and tension forces cannot "flow" at sharp angles from one cross-section to the next.
Elevation of thickened slab. It would be unrealistic to use a design depth of t2 at cross-section A-A.
A slope limit of 0.0 will not allow any change between adjacent cross sections’ top elevations and bottom elevations. This effectively trims all the cross sections in a span segment strip to have the same top and bottom elevation.
In general, we do not recommend using a slope limit over 0.25.
