Does the activation of the partial safety factor GammaM have an effect on the calculation in RF‑GLASS?


Yes, it does. Since the determination of the allowable limit stress for various glass units applies different GammaM factor according to DIN 18008, this is also included in our material library. However, the consequence if this is that by activating this option, the stiffness of the structural system is reduced by this factor.

Especially in the case of the analysis of solid loads (climatic loads), the reduced stiffness of the system has also effect on the calculated stresses and deformations.
