GGU-SLAB: Analysis using the subgrade reaction modulus method

The following analysis dialog box opens:

According to the theory of the elastically supported slab the subgrade reaction modulus also acts as a tensional spring, a physically impossible effect for slabs supported by the soil. If you activate the "Suppress tension bedding" the program checks for this effect after analysis and, if necessary, sets the subgrade reaction modulus for these areas to 0 and repeats the analysis. This is repeated until tension bedding is eliminated at all points. Please refer to Section 8.2 for details of the determination of moments.
