| Popis: | Large electrophysical apparatus (accelerators, detectors, tokamaks, stellarators) usually produce strong magnetic fields, which magnetizing surrounding ferromagnetics (steel masses). For example, concrete structures of buildings are reinforced with steel rebar that can produce a local substantial contribution into the magnetic field in the area where the service staff and magnetically sensitive equipment is located. The article describes an advanced approach to modelling magnetic properties of reinforced concrete structures taking into account the anisotropic effect due to rod layers orientations. The equivalent model has been validated in the computation of a test problem. For comparison, simulations have been carried out with a detailed 3D FE model that describes each of the steel rods. The equivalent model has required a few times less finite elements than the detailed model. A comparison of the fields obtained has demonstrated a very good match, even for the distances comparable with the rebar rod gaps.
