As of the 2017.h version, a subgrade modulus can be assigned to slabs defined in floor plans, regardless of whether they are imported or introduced by users.
The analytical model that is generated based on a mat foundation for which a subgrade modulus has been defined, will be assigned that subgrade modulus in the X, Y and Z directions. This however, can be edited for any direction.
In the “Floor plans” tab, users can consult soil pressure in the contour maps for the different loadcases and combinations. The program checks that allowable bearing pressure defined in “General data” is not exceeded and that there are no uplift points for any combination.
