Design a cross-section with uni-axial or bi-axial loads
Based on the default setting (concrete settings), SCIA Engineer will check the ratio ρM between the two moments (My & Mz).
You can set the limit of this ratio which by default it is ρM,lim = My / Mz = 0.1. So if this ratio is < 0.1, then the design will be uniaxial around My or Mz.
In addition, you can ignore this ratio and choose the design method manually.
There are three predefined options, the other two options are user defined with or without limits.
- Uniaxial around z- Design of uniaxial bending moment Mz only. My will be taken as zero.
- Uniaxial around y- Design of uniaxial bending moment My only. Mz will be taken as zero.
- Biaxial design- both moments will be considered.
