6. SLABS

CHAPTER 6 "SLABS" 18 2.6 Thickness This option automatically performs a looseness check for the identified slabs and determines the required slab thickness in mm. The calculation is done for all the plates in total. ATTENTION: Any manual modification you make to the imported plates requires recalculation of their thickness. OBSERVATIONS: Here the program, taking into account the default value for the Minimum plate thickness given in "Parameters", calculates the required one, and comparing the two values, keeps the maximum one. The required thickness is determined by the formula: hf= d+ coating, where : d (static height) >= al/30 for solid slabs d (static height) >= al/25 for plates with infill bodies d (static height) >= al/20 for slabs with ribs a: the ratio between the ideal length and the theoretical opening, given in the table paragraph 16.2. of the NRC . Select: 2.6.1 Overall for automatic calculation of the thickness of all slabs of the active level. 2.6.2 Selectively to calculate the thickness of the slabs you select by left-clicking.
