2.Verification of distribution of shear forces:

In order to guarantee the admired performance and in order to adapt the technology entirely, the distribution of shear forces has to be counterchecked. Unidome concrete shapers are admissible in all areas where the governing shear forces are less than 50% of the shear resistance of the solid flat slab.
