10C. DIMENSIONING PART 3/4

CHAPTER 10C 'DIMENSIONING' 8 In the example below: The max Mz and min Mz have been excluded. This means that the program will not check for the two extreme values of Mz. In the other checks, however, Mz is normally included in the respective hexagon. STEP 2 : If you select the automatic procedure (column Auto ) then the program calculates for each series (six) of intensive quantities which check it should make based on the values corresponding to each intensive quantity. So if in a hexadecade there are only N, My,Mz values while Mx=Qy=Qz=0 then the program will perform the checks for Bending, Axial Bending, Compression & Tensile (it will not perform the check against torsion, shear etc.). So the issue will print the 12 worst reasons, one for each intensive size. (12 rows of 6 reasons each). At this point the following should be emphasised: If you select the Auto column, the program performs the corresponding checks based on the intensities present in the corresponding hex. Thus, the individual ratio of the corresponding intensive size participates in the resulting strength ratio with its sign, which means that some sizes may have a "relieving" effect, so that the total ratio is smaller than if you had manually performed an individual check, e.g. only in axial.
