Permissible bending moment		M_adm [Nm]	26,7
Admissible load under seismic activity performance categories C1 and C2 see European Technical Assessment ETA-16/0043		C1	x		x

Admissible load when exposed to fire (R30, R60, R90, R120), see European Technical Assessment ETA-16/0043
¹⁾ The partial safety factors of the resistances y_M regulated in the evaluation/approval and a partial safety factor of the effects of γ_F = 1.4 have been taken into account. For a combination of tensile and shear loads, for the influence of the edge distance and anchor groups please see the appropriate guidelines e.g. DIN EN 1992-4. ²⁾ The concrete has normal reinforcement. Higher values are possible for higher concrete strengths.
