For the hot rating, the modulus of elasticity is reduced. I assume that this applies first to the evidence. To what extent, however, is a change in stiffness in the structure and thus a load transfer taken into account?

Answer

The modulus of elasticity of the material is reduced for the proofs according to EC 3, but not for the internal forces, since this is not intended according to the method of DIN EN 1993-1-2. It is always assumed that the structure is cold. In the calculation of the internal forces, one has to take into account only the internal constraint of temperature stress, if this is present.
