This load combination is intended for checking the characteristic serviceability limit state. It conservatively does not consider combination factors for live loads, even though the Code technically permits ψ ₀ to be applied to all accompanying variable actions. The load factors used are:

Balance Loading: 1.0 (std & alt)

Dead Loading: 1.0 (std & alt)

Live Loading: 1.0 (std) & 0.0 (alt)

Snow Loading: 0.5 (std) & 0.0 (alt)
