Hi, I am using the OptiCroSec component to optimize the shell thickness, see attached file, and I noticed that changing the material safety factors, both gammaM0 and gammaM1, yields no change in the mass of concrete. By opposition, when using the OptiReinf component, changing the gammaMs actually changes the mass of reinforcing steel. Why is the mass of concrete not influenced by the material safety factor? The goal is to use service loads and apply a greater material safety factor to allow the selection of an appropriate shell thickness, similar to the Allowable Stress Design theory.
