The loads and load combinations for serviceability depend on the serviceability limit states and on the properties of the structural materials. Information on loads and load combinations for the serviceability limit states, other than those controlled by deflection, can be found in the Commentary entitled “Deflection and Vibration Criteria for Serviceability and Fatigue Limit States” in the “Structural Commentaries (User’s Guide – NBC 2020: Part 4 of Division B)”.
