Answer:
Beam steering is the angular rotation of antennas under the effect of the present loads (wind, overload, earthquake, deformation, and so on). As an indication, for the GSM, the value of the beam steering must not exceed 1°. This limit of beam steering is often accessible in the clauses of the Technical Specifications of the project.
In RF‑/TOWER Design, it is possible to control the beam steering of antennas for the SLS design. To activate this rotation design of antennas, go to Details → Serviceability Limit State.
Une fois cette case cochée, les antennes sont accessibles dans la fenêtre 1.10.2 État limite de service des antennes. Here, you can enter the angular rotation limit of each antenna.
Après le calcul, le ratio le plus élevé est accessible dans la fenêtre 2.7 Vérification par antenne.
